Dear Shareholders:
 
     You are cordially invited to attend the 1996 Annual Meeting of Shareholders
of North Star Universal, Inc. ("NSU") to be held at 4:00 p.m. local time on June
4, 1996, at the Marriott Southwest, 5801 Opus Parkway, Minnetonka, Minnesota.
 
     As you are aware, on December 21, 1995, NSU and Michael Foods, Inc.
("Michael") entered into an Agreement and Plan of Reorganization (the
"Reorganization Agreement") pursuant to which (i) NSU Merger Co., a Delaware
corporation and wholly-owned subsidiary of NSU ("Merger Co."), will be merged
with and into Michael and Michael will become a wholly-owned subsidiary of NSU
(the "Merger"), (ii) each stockholder of Michael (other than NSU) will receive,
in exchange for each share of common stock, par value $.01 per share, of Michael
("Michael Common Stock"), held by such stockholder, one share of the common
stock, par value $.01 per share, of NSU ("NSU Common Stock"), (iii) NSU will
change its name to Michael Foods, Inc. (NSU after the consummation of the Merger
is referred to hereinafter as "New Michael") and will continue the business
previously conducted by Michael, (iv) prior to the consummation of the Merger,
NSU will transfer all of its assets and liabilities other than certain
indebtedness and other agreed upon assets and liabilities to another
wholly-owned subsidiary of NSU, ENStar Inc. ("ENStar"), (v) the outstanding
common stock of ENStar will be distributed pro rata by NSU to the shareholders
of NSU of record as of a record date just prior to the effective date of the
Merger (the "Distribution"), and (vi) immediately prior to the effective time of
the Merger, NSU will effectuate a reverse stock split (the "Reverse Stock
Split"), the ratio of the Reverse Stock Split to be determined pursuant to the
terms of the Reorganization Agreement, as described in the accompanying Proxy
Statement/Prospectus under "THE REORGANIZATION -- Effects of the
Reorganization." The above-referenced transactions are herein collectively
referred to as the "Reorganization."
 
     In addition to the election of six directors to the Board of Directors of
NSU, at the Annual Meeting you will be asked to consider and vote upon the
following proposals in connection with the Reorganization:
 
      (i)  a proposal to approve the Reorganization Agreement and the Merger;
 
      (ii) a proposal to approve the Reverse Stock Split;
 
     (iii) a proposal to approve the Distribution; and
 
     (iv)  a proposal to approve an amendment to the Restated Articles of
           Incorporation of NSU (collectively, the "NSU Proposals").
 
At the same time, Michael shareholders will be meeting to approve the
Reorganization Agreement and the Merger. Your board of directors believes that
the Reorganization is in the best interest of NSU and its shareholders and has
unanimously approved the NSU Proposals. THE BOARD UNANIMOUSLY RECOMMENDS THAT
YOU VOTE "FOR" THE NSU PROPOSALS.
 
     Pursuant to an Orderly Disposition and Registration Rights Agreement
between NSU and James H. Michael and Jeffrey J. Michael, each a member of the
Board of Directors of NSU, and two limited partnerships controlled by them (the
"Michael Family Shareholders"), the Michael Family Shareholders, which own an
aggregate of 5,685,100 shares of the outstanding NSU Common Stock (approximately
60.17% of the outstanding shares of NSU Common Stock as of the date hereof) have
agreed to vote in favor of the NSU Proposals. IF THE MICHAEL FAMILY SHAREHOLDERS
VOTE IN ACCORDANCE WITH THAT AGREEMENT, THE APPROVAL OF THE NSU PROPOSALS IS
ASSURED.
<PAGE>   5
 
     Consummation of the Reorganization is subject to certain conditions,
including approval and adoption of the Reorganization Agreement and the Merger
by the affirmative vote of the holders of a majority of the outstanding shares
of Michael Common Stock, the approval of the NSU Proposals by the affirmative
vote of the holders of a majority of the NSU Common Stock, a favorable tax
ruling from the Internal Revenue Service and the receipt of certain approvals
from regulatory authorities.
 
     The accompanying Proxy Statement/Prospectus provides detailed information
concerning the Reorganization, the NSU Proposals, and certain additional
information, which you are urged to read carefully. It is important that your
shares be represented at the annual meeting regardless of the number you hold.
Whether or not you plan to attend the annual meeting, you are requested to
complete, date, sign and return the proxy card in the enclosed postage paid
envelope. You may revoke your proxy at any time prior to its exercise at the
annual meeting by written notice of revocation to the secretary of Michael, by
signing and returning a later dated proxy or by voting in person at the annual
meeting.
 
     Please do not send in your stock certificates at this time. In the event
the Reorganization is consummated, you will be sent a letter of transmittal for
that purpose.
 
                                          Sincerely,
 
                                          Jeffrey J. Michael

THE REORGANIZATION
 
     On December 21, 1995, NSU and Michael entered into the Reorganization
Agreement pursuant to which: (i) Merger Co. will be merged with and into Michael
and Michael will become a wholly-owned subsidiary of NSU; (ii) in the Merger,
each stockholder of Michael (other than NSU) will receive, in exchange for each
share of Michael Common Stock held by such stockholder, one share of NSU Common
Stock; (iii) NSU will change its name to Michael Foods, Inc. and will continue
the business previously conducted by Michael; (iv) prior to the consummation of
the Merger, NSU will transfer all of its assets and liabilities other than
certain indebtedness and other agreed upon assets and liabilities to ENStar; (v)
the outstanding common stock of ENStar will, conditioned on the consummation of
the Merger, be distributed pro rata to the shareholders of NSU of record as of a
record date prior to the Effective Date of the Merger; and (vi) immediately
prior to the Effective Time of the Merger, NSU will effectuate the Reverse Stock
Split, the ratio of the Reverse Stock Split to be determined pursuant to the
terms of the Reorganization Agreement, as described below under "THE
REORGANIZATION -- Effects of the Reorganization."
 
EFFECT OF THE REORGANIZATION ON MICHAEL STOCKHOLDERS
 
     Upon the consummation of the Merger, each outstanding share of Michael
Common Stock, other than the Michael Common Stock owned by NSU, will be
converted into the right to receive one share of NSU
 
                                        8

Common Stock, which, after the Reorganization, is also referred to herein as New
Michael Common Stock. See "THE REORGANIZATION -- Effects of the Reorganization"
and "THE REORGANIZATION AGREEMENT -- Effects of the Reorganization on the
Stockholders of Michael and the Shareholders of NSU." For a description of the
New Michael Common Stock, see "DESCRIPTION OF NEW MICHAEL CAPITAL STOCK." For a
summary of the principal differences between the rights of holders of NSU Common
Stock before and after the Reorganization, see "COMPARISON OF RIGHTS OF NSU
SHAREHOLDERS BEFORE AND AFTER THE REORGANIZATION."
 
EFFECT OF THE REORGANIZATION ON NSU SHAREHOLDERS.
 
     Reverse Stock Split. Immediately prior to the Effective Time, NSU will
effect the Reverse Stock Split whereby each outstanding share of NSU Common
Stock will be combined into a fraction of one share of NSU Common Stock
determined by multiplying each such share by a fraction where the denominator is
the number of outstanding shares of NSU Common Stock immediately prior to the
Effective Date, and the numerator is the number of shares of Michael Common
Stock owned by NSU at such date less the number of shares of Michael Common
Stock owned by NSU which are retired in consideration for the assumption of the
"Net Indebtedness," as hereinafter defined, of NSU by New Michael. The amount of
the Net Indebtedness of NSU to be retained by New Michael is equal to the sum of
the subordinated debentures, subordinated fixed-term time certificates,
subordinated extendible time certificates and bank debt of NSU outstanding
immediately prior to the Effective Time plus the "Dissenting Shares Holdback,"
as hereinafter defined, less any cash retained by NSU at the Effective Time of
the Merger. Pursuant to the terms of the Reorganization Agreement, the amount of
the Net Indebtedness may not be less than $25 million or more than $38 million.
The Dissenting Shares Holdback is the amount mutually agreed by Michael and NSU
as a reserve to pay for the shares of NSU Common Stock as to which dissenters'
rights properly have been exercised. See "THE REORGANIZATION -- Effects of the
Reorganization" and "THE REORGANIZATION AGREEMENT -- Effects of the
Reorganization on the Stockholders of Michael and the Shareholders of NSU."
 
     Distribution. Prior to the Effective Date, NSU will transfer all of its
assets and liabilities other than the Michael Common Stock owned by NSU, all of
the outstanding common stock of Merger Co., cash in an amount to be determined
by NSU and a certain amount of NSU indebtedness to ENStar and declare a
contingent dividend of all of its ENStar Common Stock, payment of which will be
subject to the prior consummation of the Merger. Immediately after the Effective
Time, the ENStar Common Stock will be distributed by NSU as a tax-free dividend
to NSU shareholders of record as of a record date prior to the Effective Date.
See "THE DISTRIBUTION AGREEMENT." Holders of Michael Common Stock will not
receive any ENStar Common Stock as a result of the Reorganization.
 
EXCHANGE OF CERTIFICATES; DISTRIBUTION OF ENSTAR COMMON STOCK
 
     As soon as practicable after the Effective Date, The First National Bank of
Boston, or another person mutually designated by Michael and NSU, in its
capacity as exchange agent for the Merger and the Reverse Stock Split (the
"Exchange Agent"), will send a transmittal letter to each holder of Michael
Common Stock and each holder of NSU Common Stock as of the Effective Date. The
transmittal letter will contain instructions with respect to the surrender of
certificates representing the Michael Common Stock and NSU Common Stock to be
exchanged for certificates evidencing the New Michael Common Stock in the
Merger. On or prior to the Effective Date, NSU will deliver to its Exchange
Agent certificates representing all of the outstanding shares of ENStar Common
Stock. Immediately after the Effective Time, NSU will deliver to such Exchange
Agent instructions to distribute, as promptly as practicable following the
Effective Date, to each holder of record of NSU Common Stock on the record date
for the Distribution, stock certificates evidencing one share of ENStar Common
Stock for every three shares of NSU Common Stock held of record by such holder
on such record date and cash in lieu of any fractional shares of ENStar Common
Stock. See "THE REORGANIZATION -- Procedure for Exchange of Certificates."
 
MICHAEL STOCKHOLDERS AND NSU SHAREHOLDERS SHOULD NOT FORWARD CERTIFICATES TO THE
EXCHANGE AGENT UNTIL THEY HAVE RECEIVED TRANSMITTAL LETTERS. MICHAEL
STOCKHOLDERS AND NSU SHAREHOLDERS SHOULD NOT RETURN STOCK CERTIFICATES WITH THE
ENCLOSED PROXY.

OWNERSHIP OF NEW MICHAEL AFTER THE REORGANIZATION
 
     Following the Reorganization, NSU's only assets will consist of all of the
outstanding capital stock of Michael, certain contractual rights and retained
cash. In order to avoid confusion, on the Effective Date, NSU will change its
name to Michael Foods, Inc. and transactions in New Michael Common Stock will
continue to be reported on the Nasdaq National Market under the symbol MIKL.
Michael will change its name to Michael Foods of Delaware, Inc. At the date of
this Proxy Statement/Prospectus, NSU owns, directly and beneficially, 7,354,950
shares of the outstanding common stock of Michael, or approximately 38% of such
securities. Holders of Michael Common Stock immediately prior to the Merger,
excluding NSU, will own directly and beneficially approximately 77.4% to 67.6%
of New Michael Common Stock outstanding immediately after the Merger depending
upon the amount of the Net Indebtedness retained by New Michael.
Correspondingly, NSU shareholders immediately prior to the Merger will own,
directly and beneficially, approximately 22.6% to 32.4% of the outstanding New
Michael Common Stock immediately after the Merger.
 
RECOMMENDATION OF MICHAEL BOARD; MICHAEL'S REASONS FOR THE REORGANIZATION
 
     The Board of Directors of Michael (the "Michael Board") (with James H.
Michael, Jeffrey J. Michael and Miles E. Efron, each of whom is also a director
of NSU, having recused themselves from any discussions of and vote on the
proposed transaction), has determined that the Reorganization is in the best
interest of Michael and recommends that the holders of Michael Common Stock vote
in favor of the Reorganization Agreement and the Merger. The decision of the
Michael Board to enter into the Reorganization and to recommend that its
stockholders vote in favor of the Reorganization Agreement and the Merger is
based upon its evaluation of a number of factors, including, among others, the
opinion of Piper Jaffray Inc. ("Piper Jaffray") that the consideration given up
by Michael in the form of the Net Indebtedness retained by New Michael after the
Merger, in exchange for the shares of Michael Common Stock held by NSU that will
be retired in the Merger, and the exchange of Michael Common Stock for NSU
Common Stock, is fair to Michael from a financial point of view. See "THE
REORGANIZATION -- Recommendation of Michael Board; Michael's Reasons for the
Reorganization;" and "THE REORGANIZATION -- Fairness Opinions."
 
RECOMMENDATION OF NSU BOARD; NSU'S REASONS FOR THE REORGANIZATION
 
     The Board of Directors of NSU (the "NSU Board"), by unanimous vote,
determined that the consummation of the Reorganization, including the Merger,
the Reverse Stock Split and the Distribution, is in the best interest of the
holders of NSU Common Stock and recommends that the holders of NSU Common Stock
vote in favor of the NSU Proposals. The decision of the NSU Board to enter into
the Reorganization Agreement and to make the foregoing recommendations is based
upon its evaluation of a number of factors including, among others, the opinion
of Goldsmith, Agio, Helms Securities Inc. ("GAHS"), that the Reorganization is
fair to the Shareholders of NSU from a financial point of view. See "THE
REORGANIZATION -- Recommendation of NSU Board; NSU's Reasons for the
Reorganization;" and "THE REORGANIZATION -- Fairness Opinions."
 
OPINIONS OF FINANCIAL ADVISORS
 
     Michael. On December 21, 1995, Piper Jaffray rendered to the Michael Board

matters set forth in its written opinion, as of such date, that the

Stock held by NSU that will be retired in the Merger, and the exchange of
Michael Common Stock for NSU Common Stock is fair to Michael from a financial
point of view. The full text of the written opinion of Piper Jaffray dated as of
the date of this Proxy Statement/Prospectus, which sets forth the assumptions

     NSU. On December 21, 1995, GAHS rendered to the NSU Board its oral and
written opinion to the effect that the Reorganization is fair to NSU's

opinion of GAHS, dated as of the date of this Proxy Statement/Prospectus, which
sets forth the assumptions made, factors considered and limitations on the
review undertaken by GAHS is included as Appendix III to this Proxy

in its entirety. See "THE REORGANIZATION -- Fairness Opinions."
 
THE REORGANIZATION AGREEMENT
 
     Representations, Warranties and Covenants. The Reorganization Agreement
contains various representations and warranties of NSU and Michael relating to
the organization and operations of such entities. See "THE REORGANIZATION
AGREEMENT -- Representations and Warranties." In the Reorganization Agreement,
NSU and Michael have made certain covenants with respect to the conduct of their
respective businesses and certain actions to be taken between the date of the
Reorganization Agreement and the Effective Date. See "THE REORGANIZATION
AGREEMENT -- Certain Covenants."
 
     Conditions to the Reorganization. The obligations of Michael and NSU to
consummate the transactions contemplated under the Reorganization Agreement are
subject to various conditions including, but not limited to: (i) the accuracy of
representations and warranties of the other party; (ii) the receipt of a

the Reverse Stock Split and the Distribution will not result in taxable gain or
loss; (iii) the effectiveness of the registration statement filed with the
Commission under the Securities Act with regard to the shares of NSU Common

Securities Act with regard to the shares of ENStar Common Stock to be
distributed in the Distribution (the "ENStar Registration Statement"); (iv)
obtaining requisite stockholder and shareholder approvals; (v) the absence of
any injunction or other order that would prohibit or make illegal the

     Termination. The Reorganization Agreement may be terminated at any time
prior to the Effective Time, whether before or after approval of the matters
presented to the stockholders of Michael or the shareholders of NSU at their
respective Annual Meetings: (i) by mutual written consent of the Boards of
Directors of Michael and NSU; (ii) by either party, if any of the conditions to
such party's obligation to complete the transactions become impossible to
satisfy; (iii) by either party if the requisite stockholder vote or shareholder
vote has not been obtained; (iv) by either party if the transactions have not

(vi) by Michael if the Average Price of Michael Common Stock is more than $17.00
per share; and (vii) by either party if any representation or warranty of the
other party becomes untrue, subject to certain exceptions. Under certain
circumstances, Michael or NSU may recover from the other party out-of-pocket
costs, including fees and expenses of attorneys, accountants and investment
bankers, up to an aggregate of $500,000 if the Reorganization Agreement is
terminated by the other party. Entitlement to such reimbursement is the sole and
exclusive remedy of a party for any termination of the Reorganization Agreement.
See "THE REORGANIZATION AGREEMENT -- Termination," and "THE REORGANIZATION
AGREEMENT -- Expenses."
 
THE DISTRIBUTION AGREEMENT
 
     The Distribution Agreement is attached to the Reorganization Agreement as
Exhibit C and included as a part of Appendix I of this Proxy
Statement/Prospectus. The Reorganization Agreement provides that NSU will, and
will cause ENStar to, execute and deliver the Distribution Agreement prior to
the Effective Date. The Distribution Agreement requires NSU to contribute and
transfer to ENStar or an ENStar subsidiary all of NSU's right, title and
interest in and to all of NSU's assets except for certain assets to be retained
by New
 
                                       11
<PAGE>   20
 
Michael. In addition, ENStar will assume and has agreed to pay, perform and
discharge all liabilities of NSU arising at any time prior to the Effective
Time, other than certain liabilities retained by New Michael. The Distribution
is expressly conditioned on the prior consummation of the Merger and the
satisfaction of certain other conditions set forth in the Distribution
Agreement. In the Distribution, each NSU shareholder of record on the record
date for the Distribution will receive one share of ENStar Common Stock for
every three shares of NSU Common Stock held by such holder on such date, which
date will be prior to the Effective Date and prior to the Reverse Stock Split.
The Distribution Agreement also requires ENStar and New Michael to indemnify
each other for certain losses and liabilities arising before or after the
Effective Time. See "THE DISTRIBUTION AGREEMENT."
 
THE ORDERLY DISPOSITION AGREEMENT
 
     Concurrently with the execution of the Reorganization Agreement, the
Michael Family Shareholders, which own an aggregate of 5,685,100 shares of the
outstanding NSU Common Stock (approximately 60% of the outstanding shares of NSU
Common Stock as of the date hereof), and NSU entered into that certain Orderly
Disposition and Registration Rights Agreement, dated December 21, 1995 (the
"Orderly Disposition Agreement"). The Orderly Disposition Agreement is attached
as Exhibit E to the Reorganization Agreement and included as part of Appendix I
of this Proxy Statement/Prospectus. Under the Orderly Disposition Agreement, the
Michael Family Shareholders have agreed, among other things, to vote the shares
of NSU Common Stock owned by them in favor of the NSU Proposals. The Michael
Family Shareholders have also agreed to refrain for a period of two years after
the Merger from selling, pledging or otherwise disposing of any of the shares of
New Michael Common Stock owned by them if the purchaser of such shares owns or
would own more than five percent of the outstanding New Michael Common Stock,
unless New Michael is first given an opportunity to purchase such shares. The
disposition restrictions do not apply if a tender offer is made for all of the
outstanding New Michael Common Stock. In addition, the Michael Family
Shareholders are entitled during such two year period to certain registration
rights under the Securities Act with respect to the New Michael Common Stock
owned by them. Finally, during such two year period, the Michael Family
Shareholders will be entitled to designate two nominees for the Board of New
Michael (the "New Michael Board") if they collectively own ten percent or more
of the outstanding New Michael Common Stock and one nominee for director if
their ownership is below ten percent. The Michael Family Shareholders' initial
designees to the New Michael Board are Jeffrey J. Michael and Miles E. Efron.
See "THE REORGANIZATION -- Interest of Certain Persons in the Reorganization."
 
TREATMENT OF MICHAEL STOCK OPTIONS
 
     The Reorganization Agreement obligates New Michael to assume all existing
stock option plans of Michael and the stock award portion of Michael's Executive
Incentive Plan. Outstanding Michael stock options will be converted into options
to purchase New Michael Common Stock and, to the extent exercisable, may be
exercised at the stated exercise price and for an equal number of shares of New
Michael Common Stock. At April 15, 1996, Michael had granted options under these
Plans to purchase 2,054,331 shares, of which options for 1,643,904 shares were
currently exercisable. See "THE REORGANIZATION -- Effect on Stock Option Plans."
All outstanding stock options for NSU Common Stock will be exercised or canceled
prior to the Effective Time.
 
ACCOUNTING TREATMENT
 
     The Merger will be accounted for as a business combination utilizing the
reverse acquisition method with Michael being the accounting acquiror under
generally accepted accounting principles. As such, the Merger will be treated as
an acquisition using the purchase method of accounting with no change in the
recorded amount of Michael's assets and liabilities. The assets and liabilities
of NSU that are acquired as a result of the Merger will be recorded at their
fair market values. The ENStar assets and liabilities, following the
Distribution, will be recorded at their historic amounts as recorded in the
books and records of NSU. See "THE REORGANIZATION -- Accounting Treatment."

<PAGE>   21
 
CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
     The obligations of Michael and NSU to consummate the Reorganization are
subject to the receipt of the following favorable rulings from the IRS:
 
      (i) The Merger will be treated as a tax-free reorganization within the
          meaning of Section 368 of the Internal Revenue Code of 1986, as
          amended (the "Code"), and that no gain or loss will be recognized by
          any Michael stockholder upon receipt of New Michael Common Stock
          pursuant to the Merger.
 
      (ii) The Reverse Stock Split will not be treated as a stock distribution,
           or a transaction that has the effect of such a distribution, to which
           Sections 301, 305(b) or 305(c) of the Code apply. Accordingly, no
           taxable income will be recognized under such Sections by any of the
           shareholders of NSU, except for cash paid in lieu of fractional
           shares.
 
     (iii) The Distribution will qualify as a tax-free distribution under
           Sections 355 and 368(a)(1)(D) of the Code, and that no gain or loss
           will be recognized by any NSU shareholder upon the receipt of ENStar
           Common Stock pursuant to the Distribution (except upon the receipt of
           cash by an NSU shareholder in lieu of fractional shares of ENStar
           Common Stock).
 
     See "THE REORGANIZATION -- Certain Federal Income Tax Consequences."
 
REGULATORY APPROVALS
 
     The Merger is subject to the requirements of the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended (the "HSR Act"), and the rules
and regulations thereunder, which provide that certain transactions may not be
consummated until required information and materials are furnished to the
Antitrust Division of the Department of Justice and the Federal Trade Commission
("FTC") and the requisite waiting period has expired or is terminated. NSU and
Michael intend to file the required information and materials with the antitrust
division and the FTC effective prior to the end of April 1996, and the requisite
waiting period will expire prior to the end of May 1996, unless earlier
terminated. See "THE REORGANIZATION -- Regulatory Approvals."
 
DISSENTERS' RIGHTS
 
     Holders of Michael Common Stock are not entitled to dissenters' or
appraisal rights in connection with the Reorganization. Holders of NSU Common
Stock who do not vote in favor of the Distribution and who file a written
objection thereto with NSU prior to the NSU Annual Meeting or at such meeting,
but before the vote is taken, and who have otherwise complied with Section
302A.473 of the Minnesota Business Corporations Act (the "MBCA") will be
entitled to certain dissenters' rights. See "THE REORGANIZATION -- Dissenters'
Rights." If holders of more than 1% of the outstanding shares of NSU Common
Stock exercise dissenters' rights, NSU has the right under the Reorganization

     The payment of future dividends on New Michael Common Stock will be a
business decision to be made by the New Michael Board from time to time based
upon the results of operations and the financial condition of New Michael and
such other factors as the New Michael Board considers relevant. See "COMPARATIVE
PER SHARE MARKET PRICE AND DIVIDEND INFORMATION."
 
     No market currently exists for the ENStar Common Stock. ENStar has applied
to have the ENStar Common Stock approved for quotation on the Nasdaq National
Market under the symbol "ENSR." No assurance can be given that an active market
will develop or continue for the ENStar Common Stock. Management of ENStar
currently intends to retain any earnings for use in its operations and does not
anticipate paying any cash dividends in the foreseeable future.
 
     New Michael expects to continue the Nasdaq National Market listing of NSU
Common Stock, but will use the symbol MIKL, rather than NSRU, and will
discontinue the listing of the New Michael Common Stock on the Pacific Stock
Exchange.

- -------------------------
(1) These pro forma per share amounts represent the interest of a holder of a
    share of Michael Common Stock in New Michael after the Merger. The pro forma
    book value computation utilizes the book value of New Michael divided by the
    number of outstanding shares of New Michael Common Stock reduced by
    2,560,594 Retired Michael Shares. The pro forma net earnings computation for
    the year ended December 31, 1995, utilizes the net earnings of New Michael
    and the weighed average shares of Michael Common Stock reduced by 2,560,594
    Retired Michael Shares. See "THE REORGANIZATION -- Effects of the
    Reorganization" for a hypothetical calculation of such number of Retired
    Michael Shares.
 
(2) The calculation of pro forma dividends paid per share assumes the same per
    share dividend was paid.
 
(3) These pro forma per share amounts represent the interest of a holder of a
    share of NSU Common Stock in ENStar's per share book value and the net
    income from continuing operations after the Distribution. The book value per
    share and net income from continuing operations per share amounts represent
    the book value and net income from continuing operations, respectively, of
    ENStar divided by the number of outstanding shares of NSU Common Stock at
    December 31, 1995 for the book value computation and weighted average number
    of outstanding shares of NSU Common Stock for the year ended December 31,
    1995 for the net income from continuing operations computation.
 
(4) These pro forma per share amounts represent the interest of a holder of a
    share of NSU Common Stock in New Michael per share book value and net income
    from continuing operations after the Merger. The pro forma book value
    computation is computed by dividing New Michael pro forma stockholder equity
    by the number of shares of outstanding New Michael Common Stock after
    reduction for the Retired Michael Shares (19,332,001, the historical
    outstanding shares of Michael at December 31, 1995, less 2,560,594 Retired
    Michael Shares), this product is then adjusted for an assumed Reverse Stock
    Split ratio of .51 shares of New Michael Common Stock for every outstanding
    share of NSU Common Stock. The pro forma income from continuing operations
    computation is computed by dividing the New Michael pro forma net earnings
    by the New Michael weighted average shares outstanding (19,328,000, the
    historical weighted average shares of Michael Common Stock as of December
    31, 1995, less 2,560,594 Retired Michael Shares), this product is then
    adjusted for an assumed Reverse Stock Split ratio of .50 shares of New
    Michael Common Stock for every outstanding share of NSU Common Stock. The
    Reverse Stock Split ratios differ in these computations due to the use of
    the actual number of shares outstanding for the book value computation and
    the weighted average shares outstanding for the net income from continuing
    operations computation.
 
(5) The pro forma combined amounts are the total of the ENStar and the New
    Michael pro forma per share amounts.

                  RISK FACTORS RELATING TO ENSTAR COMMON STOCK
 
     In addition to the other information contained in or incorporated by
reference into this Proxy Statement/Prospectus, NSU's shareholders should
consider the following risk factors regarding ENStar and the ENStar Common Stock
that such shareholders will receive in the Distribution. All references herein
to ENStar are intended to include the operating unit of NSU that will be
transferred to ENStar in connection with the Distribution.
 
LIMITED HISTORY OF PROFITABILITY; UNCERTAINTY OF FUTURE RESULTS
 
     ENStar has a limited history of profitability. ENStar experienced operating
losses during 1991, 1992, 1993 and 1994. During 1995, ENStar generated operating
income of approximately $1 million. Americable derives its revenues from three
primary lines of business: networking products and services, cable and
connectivity products and cable assemblies. Americable has recently increased
the focus of its business on network services and its cable assembly business,
which are generally more profitable. No assurance can be made, however, that
Americable will be successful in increasing revenues from its network services
and its cable assemblies. In addition, Americable continues to make significant
investments in new sales, engineering and technical personnel.
 
     Transition's ability to maintain its present level of sales and its
historical sales growth is highly dependent upon its ability to offer new
products that meet customer's demands in a rapidly changing market, particularly
in light of the relatively short life cycle of its products. In order to achieve
market acceptance of new products, Transition plans to continue its investment
in research and development expenses. Transition had research and development
expenses of approximately $1,440,000 in 1995. There can be no assurance,
however, that its research and development efforts will result in commercially
successful new products in the future. In addition, Transition believes that
sales and marketing expenses will continue to increase in terms of absolute
dollars in an effort to differentiate its products and enhance its competitive
position.
 
     These anticipated increases in operating expenses at both Americable and
Transition may result in lower operating profit at ENStar, if the companies are
unable to maintain their respective current gross profit margins and continued
sales growth. Further, if Americable is not successful in generating higher
volumes of service revenues, its operating margins will decline and its ability
to maintain its current operating profitability could be materially adversely
affected. Based on the above factors, there can be no assurance that ENStar will
be able to increase or sustain its profitability on a quarterly or annual basis
in the future.
 
PRODUCT AND SERVICE DEVELOPMENT RISKS
 
     With respect to Transition, the market for networking products is subject
to rapid technological change, evolving industry standards and frequent new
product introductions and, therefore, requires a high level of expenditures for
research and development. Transition may be required to incur significant
expenditures to develop such product offerings. There can be no assurance that
Transition will be successful in identifying, sourcing, developing and marketing
product enhancements or new products that respond to this rapidly changing
market. Also, there can be no assurance that its product enhancements and new
products will adequately meet the requirements of the marketplace and achieve
market acceptance. A critical factor in market acceptance of product
enhancements and new products is the timely introduction of such products and
enhancements in order to take advantage of existing market opportunities.
Transition has, in the past, experienced delays in the introduction of certain
of its new products and enhancements.
 
     The markets for Americable's products and services are also characterized
by rapidly changing technology and frequent new product and service offerings by
its competitors. The introduction of new technologies can render existing
products and services obsolete or unmarketable. Americable's continued success
will depend on its ability to enhance existing products and services and to
develop and introduce, on a timely and cost-effective basis, new products and
services that keep pace with technological developments and address increasingly
sophisticated customer requirements.
 
                                       18
<PAGE>   27
 
     ENStar's business, financial condition and results of operations could be
materially adversely affected if Transition were to incur delays in developing
or introducing new products or product enhancements or if such new products or
product enhancements did not gain market acceptance or in the event that
Americable were to incur delays in sourcing and developing new products and
services or that these products and services would achieve market acceptance.
 
EXPANSION STRATEGY
 
     ENStar's expansion strategy includes both internal growth and the
identification and pursuit of acquisition opportunities at Americable.
Americable currently operates in six locations and the success and the rate of
Americable's expansion into new geographical markets will depend on a number of
factors, including general economic and business conditions affecting the
industries of Americable's customers in such markets, competition, the
availability of sufficient capital, the availability of sufficient inventory to
meet customer demand, and the ability to attract and retain qualified personnel
and operate effectively in geographic areas in which Americable has no prior
experience. As a result, there can be no assurance that Americable will be able
to achieve its planned expansion on a timely or profitable basis.
 
     With respect to Americable's identification and pursuit of acquisition
opportunities, viable acquisition candidates may not be available or not
available on terms acceptable to Americable. Furthermore, Americable has not
engaged in any significant acquisitions recently, and no assurance can be made
that Americable will be able to successfully acquire or integrate the operations
of another business into the operations and business of Americable. Americable
has no present commitments, agreements or understandings with respect to any
acquisitions.
 
     If Americable continues to grow, it may be required to make further
investments in personnel and information technology systems. Failure to
successfully hire or retain such personnel or implement such systems could have
a material adverse effect on ENStar's results of operations and financial
condition. There can be no assurance that Americable will be able to manage its
expanding operations effectively, that it will be able to maintain or accelerate
its recent growth or that Americable will be able to continue to operate
profitably.
 
FLUCTUATIONS IN QUARTERLY RESULTS
 
     ENStar's quarterly revenues and operating results have varied significantly
in the past and will likely continue to do so in the future. Quarterly revenues
and operating results may fluctuate as a result of the demand for Americable's
and Transition's products and services, the introduction of new hardware and
software technologies offering improved features, the introduction of new
products and services by competitors, changes in the level of operating
expenses, competitive conditions and economic conditions generally.
 
     At Americable, the purchase of its products and services generally involves
a significant commitment of capital, with the delays frequently associated with
large capital expenditures and required authorization procedures within an
organization. For these and other reasons, Americable's operating risks are
subject to a number of risks over which it has little or no control, including
customers' technology life cycle needs, budgetary constraints and internal
authorization reviews. Further, Americable is increasing its operating expenses,
including an increase in personnel, based on anticipated revenue growth in its
networking line of business.
 
     A variety of factors may cause period-to-period fluctuations in the
operating results of Transition. Such factors include, but are not limited to,
product mix, competitive pricing pressures, material costs and timely
availability, revenue and expenses related to new product introductions, as well
as delays in customer purchases in anticipation of new products or enhancements
by Transition or its competitors. Further, Transition plans to continue to
invest in research and development, sales and marketing and technical support
staff.
 
     ENStar's operating results could be adversely affected if it is unable to
adjust spending sufficiently in a timely manner to compensate for any unexpected
revenue shortfall. Accordingly, ENStar believes that period-to-period
comparisons of its operating results should not be relied upon as an indication
of future performance.
 
                                       19
<PAGE>   28
 
In addition, the results of any quarterly period are not indicative of results
to be expected for a full fiscal year. It is possible that in certain future
quarters, ENStar's operating results may be below the expectations of public
market analysts and investors. In such event, the price of ENStar's Common Stock
would likely be materially adversely affected.
 
DEPENDENCE ON AND NEED TO RECRUIT AND RETAIN KEY PERSONNEL
 
     ENStar's success depends to a significant extent on its ability to attract
and retain key personnel. In particular, Americable and Transition are dependent
on their respective engineering and technical personnel. Competition for such
technical personnel is intense and no assurance can be given that ENStar will be
able to recruit and to retain such personnel. The failure to recruit and to
retain management and technical personnel could have a material adverse effect
on ENStar's anticipated growth, revenues and results of operations.
 
CONCENTRATION OF REVENUES
 
     During 1995, one customer accounted for approximately 11% of Americable's
net sales, and in 1994, a different customer accounted for approximately 11% of
net sales. No other customers accounted for more than 10% of Americable's
revenues. In addition, Americable derived approximately 61% of its revenues from
its 100 largest customers. While Americable seeks to build long-term customer
relationships, revenues from any particular customer can fluctuate from period
to period due to such customer's purchasing patterns.
 
     Transition distributes its products through an expanding network of
reseller channels, which include a number of regionally based domestic and
international volume distributors and, to a lesser extent, value added
resellers. In 1995, Americable was Transition's largest domestic customer
accounting for approximately 14% of domestic net sales (9% overall).
Transition's largest international customer accounted for approximately 11% of
international net sales (4% overall). Moreover, the ten distributors that sold
the largest amount of Transition's products accounted for approximately 39% of
Transition's net sales for 1995.
 
     Any termination or significant disruption of the companies' relationships
with a number of its principal customers could have a material adverse effect on
ENStar's business, financial condition and results of operations. In addition, a
deterioration in the financial condition of any of its principal customers could
expose ENStar to the possibility of large accounts receivable write-offs, which
would adversely affect ENStar's financial condition and results of operations.
 
DEPENDENCE ON KEY SUPPLIERS AND PRODUCT SUPPLY
 
     The networking industry has experienced product supply shortages and
customer order backlogs due to the inability of certain manufacturers to supply
certain products on a timely basis. In addition, certain suppliers have
initiated new channels of distribution that increase competition for the
available product supply. There can be no assurance that suppliers will be able
to maintain an adequate supply of products to fulfill Americable's and
Transition's customer orders on a timely basis. Both Americable and Transition
have experienced product supply shortages in the past and expect to experience
such shortages from time to time in the future. Failure to obtain adequate
product supplies or fulfill customer orders on a timely basis could have a
material adverse effect on ENStar's business, financial condition, and results
of operations.
 
     A significant portion of Americable's revenues is derived from sales of
network hardware, including products of various major suppliers. During 1995
approximately 19% of the Americable's sales represented products manufactured by
Bay Networks, Inc. ("Bay Networks"). Americable's agreements with those
suppliers from which it purchases products directly generally contain provisions
for periodic renewals and for termination by the supplier without cause,
generally upon relatively short notice. Although Americable believes its
supplier relationships are good, there can be no assurance that Americable's
relationships will continue as presently in effect. The loss of a major
supplier, the deterioration of Americable's relationship with a major supplier
or the failure of Americable to establish good relationships with major new
suppliers as they develop could have a material adverse effect on ENStar's
business.
 
                                       20
<PAGE>   29
 
INVENTORY MANAGEMENT
 
     The networking industry is characterized by rapid product improvement and
technological change resulting in relatively short product life cycles and rapid
product obsolescence, which can place inventory at considerable valuation risk.
Some of Transition's products include components that are currently available
from limited sources and require long order lead times. Because of the long lead
times along with Transition's desire to be responsive to customer demand,
Transition has maintained higher inventory levels compared to other networking
manufacturers. Due to the ongoing risk of product obsolescence and changes in
customer demand, there can be no assurances that Transition will be able to
successfully manage its existing and future inventories.
 
     Although it is industry practice for Americable's suppliers to provide
price protection to Americable intended to reduce the risk of inventory
devaluation, such policies are subject to change. Americable also has the option
of returning, subject to certain limitations, a percentage of its current
product inventories each quarter to certain manufacturers as it assesses each
product's current and forecasted demand. The amount of inventory that can be
returned to suppliers varies under Americable's agreements and such return
policies may provide only limited protection against excess inventory. There can
be no assurance that suppliers will continue such policies, that unforeseen new
product developments will not affect Americable adversely or that Americable can
successfully manage its existing and future inventories. Any inventory
adjustments could adversely affect ENStar's financial condition and results of
operations.
 
COMPETITION
 
     Each of ENStar's businesses face substantial competition from a large
number of companies, some of which are larger, have greater financial resources,
broader name recognition and, in many cases, lower product and operating costs
than ENStar.
 
     The industry in which Transition operates is highly competitive, and
Transition believes that such competition will continue to intensify. The
industry is characterized by rapid technological change, short product
life-cycles, frequent product introductions and evolving industry standards.
Transition competes with a number of independent companies focused on the LAN
market, including companies with significantly greater financial resources, more
extensive business experience, and greater market and service capabilities than
Transition. There can be no assurance that ENStar will be able to compete
successfully.
 
     ENStar expects to face further competition from new market entrants and
possible alliances between competitors in the future. Certain of ENStar's
current and potential competitors have greater financial, technical, marketing
and other resources than ENStar. As a result, they may be able to respond more
quickly to new or emerging technologies and changes in customer requirements or
to devote greater resources to the development, promotion and sale of their
products and services than ENStar. No assurance can be given that ENStar will be
able to compete successfully against current and future competitors. See
"BUSINESS OF ENStar -- Competition."
 
SHARES ELIGIBLE FOR FUTURE SALE
 
     Sales of a substantial number of shares of ENStar Common Stock in the
public market following the Distribution could adversely affect the market price
for the ENStar Common Stock. Upon consummation of the Reorganization the Michael
Family Shareholders, in the aggregate, will beneficially own approximately
1,895,000 shares, or approximately 60%, of the outstanding ENStar Common Stock.
 
ABSENCE OF PRIOR PUBLIC MARKET AND POSSIBLE VOLATILITY OF STOCK PRICE
 
     Prior to this offering, there has been no public market for the ENStar
Common Stock. There can be no assurance that, following this offering, an active
trading market for the ENStar Common Stock will develop or be sustained,
particularly in light of the limited number of shares being distributed in the
Distribution. The market price of the ENStar Common Stock could be subject to
significant fluctuations in response to variations in quarterly operating
results, changes in the market value of its CorVel investment, changes in
 
                                       21
<PAGE>   30
 
earnings estimates by analysts, general conditions in the industries in which
ENStar's customers compete and other events or factors. In addition, the stock
market, from time to time, has experienced extreme price and volume fluctuations
which have particularly affected the market price for companies in ENStar's and
CorVel's industries, and which have often been unrelated to the operating
performance of such companies. These broad fluctuations may adversely affect the
market price of the ENStar Common Stock.
 
POSSIBLE VOLATILITY OF CORVEL STOCK PRICE
 
     CorVel, in its reports and other information prepared and filed by it with
the Commission, has indicated that the market price of the CorVel Common Stock
may be highly volatile. CorVel has also indicated that factors such as
variations in CorVel's revenues, earnings and cash flow, general market trends
in the workers' compensation managed care market, and announcements of
innovations by CorVel or its competitors could cause the market price of the
CorVel Common Stock to fluctuate substantially. Specifically, CorVel has
reported that the quarter to quarter percentage growth in operating results for
CorVel's two most recently completed fiscal quarters was lower than the growth
rates historically experienced by CorVel. CorVel's slower growth rate in those
two fiscal quarters was partially attributable to a reduction in the growth rate
of health care expenditures nationally, contributing to a reduction in claims
processed by CorVel. There can be no assurance that CorVel's growth rate in the
future, if any, will be at or near historical levels. In addition, the stock
market has in the past experienced price and volume fluctuations that have
particularly affected companies in the health care and managed care markets
resulting in changes in the market price of the stock of many companies which
may not have been directly related to the operating performance of those
companies. Such broad market fluctuations may adversely affect the market price
of the CorVel Common Stock, which in turn may adversely affect the market price
of the ENStar Common Stock.
 
CERTAIN RISKS PERTAINING TO THE CORVEL COMMON STOCK
 
     CorVel, in its reports and other information prepared and filed by it with
the Commission, has indicated that an investment in the CorVel Common Stock
involves a high degree of risk, including the potential adverse impact of
government regulations, possible litigation and legal liability, competition,
changes in market dynamics, dependence on key personnel and risks related to
CorVel's growth strategy. These risks are described in more detail in the
reports and other information prepared and filed by CorVel with the Commission.

VOTING RIGHTS; VOTES REQUIRED FOR APPROVAL
 
     Michael. The Michael Board has fixed the close of business on April 15,
1996, as the Michael Record Date. Only holders of record of shares of Michael
Common Stock on the Michael Record Date are entitled to notice of and to vote at
the Michael Annual Meeting. As of April 15, 1996, there were 19,379,274 shares
of Michael Common Stock outstanding and entitled to vote held by approximately
       stockholders of record.
 
     Each holder of record, as of the Michael Record Date, of Michael Common
Stock is entitled to cast one vote per share. The presence, in person or by
proxy, of the holders of a majority of the outstanding shares of Michael Common
Stock entitled to vote is necessary to constitute a quorum at the Michael Annual
Meeting.
 
     Under Delaware law, the affirmative vote, in person or by proxy, of the
holders of a majority of the shares of Michael Common Stock outstanding on the

nine board nominees who receive the highest number of votes will be elected
directors of Michael and a plurality of votes cast on all other matters will be
required to approve such matters.
 
     As of April 15, 1996, directors, nominees and executive officers of Michael
as a group (18 persons) beneficially owned 8,178,958 shares of Michael Common
Stock, or approximately 42.2% of those shares of Michael Common Stock
outstanding as of such date. As of April 15, 1996, NSU beneficially owned
7,354,950 shares of Michael Common Stock or approximately 38% of the shares of
Michael Common Stock outstanding as of such date. The Michael shares
beneficially owned by NSU are included in the shares beneficially owned by
directors and executive officers.
 
     THE BOARD OF DIRECTORS OF MICHAEL RECOMMENDS THAT HOLDERS OF MICHAEL COMMON
STOCK VOTE FOR THE MICHAEL PROPOSAL AND FOR EACH OF THE NOMINEES FOR ELECTION TO
THE BOARD OF DIRECTORS OF MICHAEL.
 
     NSU. The NSU Board has fixed the close of business on April 15, 1996 as the
NSU Record Date. Only holders of record of shares of NSU Common Stock on the NSU
Record Date are entitled to notice of and to vote at the NSU Annual Meeting. On
April 15, 1996, there were        shares of NSU Common Stock outstanding and
entitled to vote at the NSU Meeting held by approximately        shareholders of
record.
 
     Each holder of record, as of the NSU Record Date, of NSU Common Stock is
entitled to cast one vote per share. The presence, in person or by proxy, of the
holders of a majority of the outstanding shares of NSU Common Stock entitled to
vote is necessary to constitute a quorum at the NSU Annual Meeting.
 
     Under Minnesota law, the affirmative vote, in person or by proxy, of the
holders of a majority of the shares of NSU Common Stock outstanding on the NSU
Record Date and entitled to vote is required to approve and adopt the NSU
Proposals. The affirmative vote of a majority of the shares of NSU Common Stock
present or represented by proxy and entitled to vote at the NSU Annual Meeting
is required to elect each of the nominees as Directors of NSU for the ensuing
year or until the consummation of the Reorganization.
 
     As of April 15, 1996, directors and executive officers of NSU as a group
beneficially owned approximately        shares of NSU Common Stock or
approximately    % of NSU Common Stock outstanding as of the NSU Record Date.
The Michael Family Shareholders beneficially owned 5,685,100 shares of NSU
Common Stock, or approximately 60% of the NSU Common Stock outstanding as of the
NSU Record Date, and have agreed in the Orderly Disposition Agreement to vote
such shares in favor of each of the Merger, the Reverse Stock Split and the
Distribution. See "THE REORGANIZATION -- Interest of Certain Persons in the
Reorganization."
 
                                       23
<PAGE>   32
 
     THE BOARD OF DIRECTORS OF NSU UNANIMOUSLY RECOMMENDS THAT HOLDERS OF NSU
COMMON STOCK VOTE FOR EACH OF THE NSU PROPOSALS AND FOR EACH OF THE NOMINEES FOR
ELECTION TO THE BOARD OF DIRECTORS OF NSU.
 
PROXIES
 
     Michael. Votes cast by proxy or in person at the Michael Annual Meeting
will be tabulated by the election inspector appointed for the meeting. All
shares of Michael Common Stock represented by properly executed proxies received
prior to or at the Michael Meeting and not revoked will be voted in accordance
with the instructions indicated in such proxies. If no instructions are
indicated on a properly executed returned proxy, such proxy will be voted FOR
the Michael Proposal. A properly executed proxy marked "ABSTAIN" (or a proxy
marked "withhold vote for" as to the election of directors), although counted
for purposes of determining whether there is a quorum, will not be voted.
Accordingly, since the affirmative vote of a majority of the shares of Michael
Common Stock on the Michael Record Date represented in person or by proxy and
entitled to vote is required for approval of the Michael Proposal, a properly
executed proxy marked "ABSTAIN" will have the effect of a vote against the
Michael Proposal. If a broker indicates on a proxy that it does not have
discretionary authority as to certain shares to vote on a particular matter,
those shares will not be considered as present and entitled to vote with respect
to that matter.
 
     NSU. Votes cast by proxy or in person at the NSU Annual Meeting will be
tabulated by the election inspector appointed for the meeting. All shares of NSU
Common Stock represented by properly executed proxies received prior to or at
the NSU Meeting and not revoked will be voted in accordance with the
instructions indicated in such proxies. If no instructions are indicated on a
properly executed returned proxy, such proxy will be voted FOR the NSU
Proposals. A properly executed proxy marked "ABSTAIN" (or a proxy marked
"withhold vote for" as to the election of directors), although counted for
purposes of determining whether there is a quorum, will not be voted.
Accordingly, since the affirmative vote of a majority of the shares of NSU
Common Stock outstanding on the NSU Record Date, represented in person or by
proxy and entitled to vote, is required for approval of each of the NSU
Proposals, a properly executed proxy marked "ABSTAIN" with respect to any such
proposal will have the effect of a vote against such proposal. If a broker
indicates on the proxy that it does not have discretionary authority as to
certain shares to vote on a particular matter, those shares will not be
considered as present and entitled to vote with respect that matter.
 
     It is not expected that any matter not referred to herein will be presented
for action at the Michael and NSU Annual Meetings. If any other matters are
properly brought before the Michael Annual Meeting or the NSU Annual Meeting,
the persons named in the proxies will have discretion to vote on such matters in
accordance with their best judgment. However, shares represented by proxies that
have been voted "AGAINST" the Michael Proposal, or any of the NSU Proposals, as
the case may be, will not be used to vote "FOR" postponement or adjournment of
the Michael Annual Meeting or the NSU Annual Meeting, as the case may be, for
the purpose of allowing additional time for soliciting additional votes "FOR"
the Michael Proposal or the NSU Proposals, as the case may be. The grant of a
proxy will also confer discretionary authority on the persons named in the proxy
as proxy appointees to vote in accordance with their best judgment on matters
incident to the conduct of the Annual Meetings, including (except as stated in
the preceding sentence) adjournment for the purpose of soliciting additional
votes.
 
     Revocation of Proxies. A stockholder or shareholder giving a proxy may
revoke it at any time prior to the voting of the proxy by filing with the
secretary of Michael or NSU, as the case may be, a written notice of revocation
or another proxy bearing a later date. Unless otherwise noted on the proxy, the
proxies will vote FOR the proposals set forth herein. Any written notice of
revocation or subsequently dated Michael proxy should be mailed or delivered to
Michael Foods, Inc., 324 Park National Bank Building, 5353 Wayzata Boulevard,
Minneapolis, Minnesota 55416; Attention: Secretary. Any written notice of
revocation or subsequently dated NSU proxy should be mailed or delivered to
North Star Universal, Inc., 610 Park National Bank Building, 5353 Wayzata Blvd.,
Minneapolis, MN 55416, Attention: Secretary. A stockholder or shareholder may
also revoke his or her proxy by attending the Michael Annual Meeting or the NSU
Annual Meeting and voting in person. Attendance at the Michael Annual Meeting or
the NSU Annual Meeting will not in itself constitute the revocation of a proxy.

     Solicitation of Proxies. Each party will bear its own costs with respect to
the Annual Meetings including the cost of preparing, assembling and mailing the
Notice of Annual Meeting, this Proxy Statement/ Prospectus and the form of
proxy, including the reimbursement of banks, brokers and other nominees for
forwarding proxy materials to beneficial owners. Proxies may also be solicited
personally or by telephone by directors, officers and regular employees of
Michael or NSU who will receive no additional compensation.
 
     THE MATTERS TO BE CONSIDERED AT THE MICHAEL AND NSU ANNUAL MEETINGS ARE OF
IMPORTANCE TO THE MICHAEL STOCKHOLDERS AND THE NSU SHAREHOLDERS. ACCORDINGLY,
MICHAEL STOCKHOLDERS AND NSU SHAREHOLDERS ARE URGED TO READ AND CAREFULLY
CONSIDER THE INFORMATION PRESENTED IN THIS PROXY STATEMENT/PROSPECTUS, AND TO

                               THE REORGANIZATION
 
     The following information describes certain aspects of the Reorganization.
This description does not purport to be complete and is qualified in its
entirety by reference to the Appendices hereto, including the Reorganization
Agreement and the exhibits thereto, which are attached to this Proxy
Statement/Prospectus as Appendix I and are incorporated herein by reference. All
shareholders are urged to read Appendix I in its entirety. See also "THE
REORGANIZATION AGREEMENT."
 
EFFECTS OF THE REORGANIZATION
 
     Prior to the consummation of the Merger, NSU will contribute all of its
assets and liabilities other than certain indebtedness and other agreed upon
assets and liabilities to ENStar. See "THE REORGANIZATION AGREEMENT -- Effects
of the Reorganization on the Stockholders of Michael and the Shareholders of
NSU." Upon consummation of the Reorganization on the Effective Date of the
Merger: (i) Merger Co. will be merged with and into Michael and Michael will
become a wholly-owned subsidiary of NSU; (ii) each stockholder of Michael (other
than NSU) will receive, in exchange for each share of Michael Common Stock held
by such stockholder, one share of New Michael Common Stock; (iii) NSU will
change its name to Michael Foods, Inc. and will continue the business previously
conducted by Michael; (iv) NSU will effectuate the Reverse Stock Split; and (v)
NSU will effectuate the Distribution, whereby all of the outstanding ENStar
Common Stock will be distributed pro rata to the shareholders of NSU of record
as of a record date just prior to the Effective Date of the Merger.
 
     As part of the negotiations with respect to the structure of the
Reorganization, Michael requested that, in order to avoid confusion on the part
of holders of Michael Common Stock, in the Merger each holder of Michael Common
Stock would receive one share of NSU Common Stock in exchange for each share of
Michael Common Stock held by such stockholder. In order to accommodate this
request, the Reorganization was structured so that the number of outstanding
shares of NSU Common Stock would be reduced through the Reverse Stock Split. In
the Reverse Stock Split, each outstanding share of NSU Common Stock will be
converted into a fraction of one share of New Michael Common Stock determined by
multiplying each such share by a fraction where the denominator is the number of
outstanding shares of NSU Common Stock immediately prior to the Effective Date
and the numerator is the number of shares of Michael Common Stock owned by NSU
at such date less the number of shares of Michael Common Stock owned by NSU
which are retired in consideration for the Net Indebtedness retained by New
Michael. For purposes of the Reorganization Agreement, Net Indebtedness is
defined to be the amount of outstanding NSU subordinated debentures and
subordinated fixed-term or extendible time certificates and the Dissenting
Shares Holdback, less any cash retained by NSU at the time of the Merger. Under
the terms of the Reorganization Agreement, the Net Indebtedness retained by NSU
may not be less than $25,000,000 nor more than $38,000,000. The number of shares
of Michael Common Stock to be retired (the "Retired Michael Shares") in
consideration for the Net Indebtedness will be determined by dividing the amount
of Net Indebtedness by the average market price of the Michael Common Stock for
the twenty trading days ending on the third trading day prior to the Effective
Date of the Merger (the "Average Price of Michael Common Stock") after applying
a certain percentage discount to the Average Price of Michael Common Stock (the
"Discount Factor"). The Discount Factor will be based upon the amount of Net
Indebtedness, ranging from .92 at $25,000,000 to .90 beginning at $33,750,000,
resulting in an effective discount of 8% to 10%, respectively. See "THE
REORGANIZATION AGREEMENT -- Effects of the Reorganization on the Stockholders of
Michael and the Shareholders of NSU."

OR LOWER THAN THE AMOUNTS PRESENTED BELOW. THE PRO FORMA ASSUMPTIONS USED BELOW
ARE DERIVED FROM THE UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS
AND THE NOTES THERETO:
 
     Pro Forma Assumptions:
 
        The Average Price of Michael Common Stock: $11.55 per share (the average
        of the closing prices of a share of Michael Common Stock for each of the
        20 trading days ending on the third trading day prior to December 31,
        1995)
 
        Net Indebtedness: $27,061,000
 
        Discount Factor: .915 (a discount of 8.5%)
 
        Aggregate number of outstanding shares of NSU Common Stock: 9,448,000
 
        Aggregate number of outstanding shares of Michael Common Stock held by
        NSU: 7,354,950
 
     Pro Forma Calculation of the Retired Michael Shares:
 
        a.   Aggregate number of Retired
             Michael Shares                =            Net Indebtedness

                                                   Stock X Discount Factor
        b.   Aggregate number of Retired
             Michael Shares                =    $27,061,000

                                               $11.55 X .915
        c.   Aggregate number of Retired
             Michael Shares                =   2,560,594
 
     Pro Forma Calculation of the Reverse Stock Split Ratio:
 
        a.   Ratio   =   (Aggregate number of outstanding shares of Michael 
                          Common Stock held by NSU less Aggregate number of 
                                      Retired Michael Shares)
                         -----------------------------------------------------
                            Aggregate number of outstanding shares of NSU 
                                         Common Stock
        b.   Ratio   =   (7,354,950 - 2,560,594)

                                9,448,000
        c.   Ratio   =   .51
 
     Under the hypothetical example provided above, in the Reverse Stock Split
each share of NSU Common Stock issued and outstanding immediately prior to the
Effective Time would be combined into .51 shares of New Michael Common Stock.
 
     All shares of Michael Common Stock held by NSU will not be converted into
shares of New Michael Common Stock in the Merger and will automatically be
canceled and retired. Each certificate previously representing shares of NSU
Common Stock or Michael Common Stock not held by NSU will thereafter represent
the right to receive a certificate representing shares of New Michael Common
Stock.
 
     For a description of the procedures for exchanging NSU Common Stock or
Michael Common Stock for New Michael Common Stock and, in the case of NSU Common
Stock, for payment of cash in lieu of the issuance of fractional shares, see "--
Procedure for Exchange of Certificates."
 
EFFECTIVE TIME
 
     If the Michael Proposal is approved and adopted by the requisite vote of
the stockholders of Michael, the NSU Proposals are approved and adopted by the
requisite vote of the shareholders of NSU and the other conditions to the
Reorganization are satisfied (or waived to the extent permitted), the Merger
will be
 
                                       27
<PAGE>   36
 
consummated and effected at the time a Certificate of Merger is filed with the
Secretary of State of the State of Delaware.
 
     The Reorganization Agreement provides that NSU and Michael will cause the
Effective Date to occur as promptly as practicable, but in no event later than
ten business days after the approval and adoption of the Michael Proposal by the
requisite vote of the stockholders of Michael, the approval and adoption of the
NSU Proposals by the requisite vote of the shareholders of NSU and satisfaction
(or waiver, to the extent permitted) of the other conditions contained in the
Reorganization Agreement. The Reorganization Agreement may be terminated by
either NSU or Michael in certain circumstances, notwithstanding the prior
approval and adoption of the Reorganization Agreement by their respective
shareholders and stockholders. See "THE REORGANIZATION AGREEMENT --
Termination."
 
BACKGROUND OF THE REORGANIZATION
 
     In March 1987, NSU formed Michael to consolidate and focus development of
NSU's food businesses, and shortly thereafter Michael completed an initial
public offering of approximately 36% of its outstanding common stock. Since that
time, NSU's ownership of Michael has been reduced from approximately 64% to
approximately 38% of the outstanding Michael Common Stock through sales by NSU
of Michael Common Stock and additional issuances of Michael Common Stock.
 
     For many years, both before and after the initial public offering of
Michael's Common Stock, NSU raised funds to finance acquisitions and support its
operations by offering and selling subordinated debentures and subordinated
fixed-term and extendible time certificates to the public. Debt service for this
indebtedness was provided through the reinvestment of maturing obligations by
investors, sales of assets and cash flow generated from NSU's operating
subsidiaries. Since the initial public offering of Michael in 1987, however, NSU
has not had the use of cash flow generated by Michael's operations other than
quarterly Michael dividends. Also, in June 1991, CorVel, formerly a wholly owned
subsidiary of NSU, completed an initial public offering of its common stock.
After the CorVel initial public offering, NSU ceased to have the use of cash
flow generated by CorVel. CorVel has not paid dividends on its common stock in
the past.
 
     As a result of these transactions, NSU has experienced cash flow deficits
from operations, which has resulted in greater reliance by NSU on the sale of
subordinated fixed-term and extendible time certificates to finance continuing
operations and service its indebtedness. In response to this situation, NSU's
senior management has, for many years, considered various alternative strategies
and transactions to substantially reduce the amount of NSU's indebtedness and to
permit its shareholders to realize the substantial value of NSU's interest in
Michael. One obvious strategic alternative has always been to participate in a
tax-advantaged transaction involving Michael.
 
     From time to time since 1990, NSU and Michael senior management have had
discussions concerning various possible tax-advantaged transactions that would
result in all or a portion of NSU's substantial ownership interest in Michael
being held directly by NSU's shareholders. Also, certain of the transactions
discussed involved the assumption of some or all of NSU's outstanding
indebtedness in consideration of the retirement of some of the Michael Common
Stock held by NSU. Although a number of alternative transactions and transaction
structures were discussed, agreement was never reached on any particular
transaction, transaction structure or related financial terms and none of these
discussions progressed beyond the preliminary discussion stage.
 
     In the summer of 1994, Jeffrey J. Michael, President and Chief Executive
Officer of NSU, contacted Gregg A. Ostrander, President and Chief Executive
Officer of Michael, to request that Michael and NSU hold discussions again in an
effort to structure a mutually acceptable transaction that would provide for the
assumption by Michael of some or all of NSU's outstanding indebtedness and
permit NSU's shareholders to directly own NSU's interest in Michael. A number of
meetings between senior management of both companies followed in the fall of
1994, and continued off and on through the spring of 1995. During this time the
fundamental elements required by each of NSU and Michael in any such transaction
between them were discussed. These elements included the following: (i) any such
transaction could not result in federal income tax to the parties or their
respective shareholders or stockholders; (ii) the amount of NSU indebtedness
 
                                       28
<PAGE>   37
 
assumed by Michael in any such transaction had to be within parameters to be
agreed upon; (iii) the Michael Common Stock to be retained in consideration for
the debt assumed in any such transaction had to be valued at a discount to the
market; and (iv) Michael had to be protected from the liabilities of NSU
relating to the operations of NSU (other than its investment in Michael Common
Stock). Michael and its financial advisors also concluded that the transfer of
all other assets and liabilities of NSU to a separate company to be spun-off to
the NSU shareholders or some other disposition of such assets and satisfaction
of such liabilities was necessary in order to avoid higher costs of capital that
would otherwise occur if such assets and liabilities were retained after the
Reorganization and to avoid the adverse impact on the value of Michael Common
Stock if New Michael were engaged in businesses unrelated to its core food
processing and distribution businesses. As a result of these discussions, senior
management of both companies, with the assistance of their respective tax and
legal advisors, developed a general transaction structure proposal that
satisfied the parties' fundamental requirements. No agreement was reached,
however, on the financial terms, or on certain of the other terms of this
proposal.
 
     Once a potentially acceptable transaction structure proposal had been
developed, advisors of both companies were directed to obtain a preliminary
indication from the IRS as to the tax treatment of the proposal. Discussions
with the IRS occurred during the spring and summer of 1995, which led senior
management of both companies to conclude that there were reasonable prospects
for receipt of a favorable ruling concerning the tax-free nature of the
transaction structure proposal.
 
     Beginning in September 1995, NSU and Michael began meetings involving
senior management and their respective legal, tax and financial advisors to
discuss the financial and other terms relating to the transaction structure
proposal that had been developed and discussed with the IRS. These discussions
continued in October, during which tentative agreement was reached between the
senior managements of NSU and Michael as to certain of the principal terms of
the transaction proposal. On October 27, 1995, immediately following Michael's
regular quarterly board meeting, Michael's management informed the Michael Board
of the status of negotiations with NSU and the principal terms of the
transaction proposal that was currently under consideration by Michael senior
management. Messrs. Jeffrey J. Michael, James H. Michael and Miles E. Efron,
each a member of the board of directors of both NSU and Michael, at the request
of Michael, did not participate in this discussion. At the NSU Board meeting
held on November 7, 1995, NSU's management and its financial advisor discussed
with the NSU Board the principal terms of the transaction proposal that was
currently under consideration by NSU senior management. The NSU Board, after
such discussion, directed and authorized certain officers of NSU to negotiate
the terms of a definitive agreement with respect to the transaction proposed,
subject to final board review and approval.
 
     Over the next several weeks, the terms of the definitive agreement were
negotiated and a definitive agreement was presented to each of the NSU and
Michael Boards at separate meetings held on December 21, 1995. Messrs. Michael,
Michael and Efron recused themselves from participation in the meeting of the
Michael Board. The Boards of Directors of NSU and Michael approved the
Reorganization Agreement at their respective meetings held on that date. The
Reorganization Agreement was executed by NSU and Michael later that same day.
 
RECOMMENDATION OF MICHAEL BOARD; MICHAEL'S REASONS FOR THE REORGANIZATION
 
     THE MICHAEL BOARD UNANIMOUSLY RECOMMENDS THAT HOLDERS OF MICHAEL COMMON
STOCK VOTE FOR THE MICHAEL PROPOSAL.
 
     Michael's Reasons for the Transactions. On December 21, 1995, the Michael
Board met to consider the Merger and the transactions contemplated thereby.
Michael's senior management, Michael's legal and accounting advisors and Piper
Jaffray, its investment banker, made presentations to the Michael Board and
discussed with the Michael Board their views and analyses of various aspects of
the proposed transactions. The Michael Board reviewed and considered, among
other things, the background of the proposed transaction, Michael's strategic
alternatives, financial and valuation analyses of the transaction, the terms of
the Reorganization and the other matters described herein. Piper Jaffray gave an
opinion that, based upon the matters presented to the Michael Board and as set
forth in its opinion, as of such date, the consideration paid
 
                                       29
<PAGE>   38
 
by Michael in the form of Net Indebtedness retained by New Michael for the
Retired Michael Shares and the exchange of Michael Common Stock for New Michael
Common Stock is fair to Michael from a financial point of view. See "-- Fairness
Opinions."
 
     In view of the variety of factors considered in connection with its
evaluation of the Reorganization, the Michael Board did not quantify or
otherwise attempt to assign relative weights to the specific factors considered
in reaching its determination. In reaching its determination to recommend
approval of the transactions, the Michael Board consulted with Michael
management, as well as legal counsel, accounting and tax advisors, and its
investment banker. The Michael Board concluded that the Reorganization will
allow Michael to acquire a large block of its stock at a discount from the
market price of such stock which Michael believes will be accretive to earnings
per share in 1996 and 1997. The effective redemption of Michael shares owned by
NSU should also remove the market's perceived adverse effect of NSU holding such
a large position in Michael and should increase the liquidity of Michael Common
Stock. The Michael Board concluded that the amount of indebtedness to be assumed
in the Reorganization would not have a material adverse affect on Michael.
Finally, the Michael Board authorized the Reorganization, in part, based on
NSU's willingness to complete the Distribution.
 
     The Michael Board believes that the terms of the Reorganization and the
transactions contemplated thereby are in the best interests of Michael and its
stockholders. Accordingly, the Michael Board has approved the Reorganization
Agreement and the Merger and recommends approval thereof by the stockholders of
Michael.
 
RECOMMENDATION OF NSU BOARD; NSU'S REASONS FOR THE REORGANIZATION
 
     THE NSU BOARD UNANIMOUSLY RECOMMENDS THAT HOLDERS OF NSU COMMON STOCK VOTE
FOR THE NSU PROPOSALS.
 
     NSU's Reasons for the Reorganization. On December 21, 1995, the NSU Board
met to consider the Reorganization, the terms of the Reorganization Agreement
and Distribution Agreement and the transactions contemplated thereby. NSU's
senior management and representatives of NSU's legal advisor and GAHS, its
independent financial advisor, made presentations to the NSU Board and discussed
with the NSU Board their views and analyses of various aspects of the proposed
transaction. The NSU Board reviewed and considered, among other things, the
background of the proposed transaction, NSU's strategic alternatives, financial
and valuation analyses of the transaction, the terms of the Reorganization
Agreement and the Distribution Agreement, the Merger, the Distribution, the New
Articles and the other matters described herein. GAHS provided an opinion that,
based upon the matters presented to the NSU Board and as set forth in its
opinion, as of such date, that the Reorganization was fair to the shareholders
of NSU from a financial point of view. See "-- Fairness Opinions."
 
     In view of the variety of factors considered in connection with its
evaluation of the Reorganization, the NSU Board did not quantify or otherwise
attempt to assign relative weights to the specific factors considered in
reaching its determination. In reaching its determination, the NSU Board
consulted with NSU management, as well as its legal counsel and financial
advisor, and considered a number of factors. The NSU Board considered that the
Reorganization will relieve NSU's operating businesses of significant debt
service obligations with respect to the Net Indebtedness of NSU to be assumed by
New Michael. The NSU Board also considered the advantages of avoiding income
taxation at the corporate level on NSU's holdings of Michael Common Stock while
providing its shareholders with a direct financial interest in Michael. Further,
the NSU Board considered that the Distribution would allow NSU's shareholders to
continue to hold an interest in NSU's other assets and that the Distribution was
required by Michael in order to avoid higher costs of capital to Michael.
 
     The NSU Board believes that the consummation of the Reorganization,
including the execution of the Reorganization Agreement, the Merger, the Reverse
Stock Split, the Distribution and the New Articles are in the best interests of
NSU and its shareholders. Based on these considerations, the NSU Board has
unanimously approved the Merger, the Reverse Stock Split, the Distribution and
the New Articles and
 
                                       30
<PAGE>   39
 
authorized the execution of the Reorganization Agreement and Distribution
Agreement and recommended approval thereof by the shareholders of NSU.
 
FAIRNESS OPINIONS
 
     Opinion of Michael's Financial Advisor. Michael retained Piper Jaffray as
its investment banker in connection with the Reorganization. Piper Jaffray is an
investment banking firm engaged, among other things, in the valuation of
businesses and their securities in connection with mergers and acquisitions,
underwriting and secondary distributions of securities, private placements and
valuations for estate, corporate and other purposes. Piper Jaffray was selected
by Michael because of its reputation as a recognized investment banking firm and
its familiarity with Michael and its respective component businesses. Piper
Jaffray makes a market in Michael's Common Stock, provides research coverage for
Michael, and acted as co-manager of public offerings of Michael Common Stock in
1987, 1988 and 1991 and as placement agent for an offering of senior notes in
1989.
 
     Piper Jaffray delivered written opinions to the Michael Board dated as of
December 21, 1995 and on or about the date of this Proxy Statement/Prospectus,
that, based upon and subject to the matters set forth in its written opinion as
of such dates, the effective price per share Michael is paying NSU, in the form
of the Net Indebtedness retained by New Michael, for the Retired Michael Shares
and the exchange of Michael Common Stock for New Michael Common Stock is fair,
from a financial point of view, to Michael. The full text of the written opinion
of Piper Jaffray, dated as of the date of this Proxy Statement/Prospectus, is
set forth as Appendix II to this Proxy Statement/Prospectus and describes the
assumptions made, matters considered and limits on the review undertaken. The
following summary of the opinion is qualified in its entirety by reference to
the full text of the opinion attached hereto as Appendix II. Michael
stockholders are urged to read the opinion in its entirety. The assumptions
made, matters considered and limits on the review undertaken in the opinion
dated the date of this Proxy Statement/Prospectus are substantially the same as
those contained in the opinion dated December 21, 1995.
 
     Piper Jaffray's opinion addresses only the fairness of the Reorganization
from a financial point of view to Michael and does not constitute a
recommendation to any stockholder of Michael as to how such stockholder should
vote with respect to the approval of the Reorganization. In connection with its
opinion, Piper Jaffray was not requested to opine as to, and their opinion does
not address, the merits of the basic business decision to proceed with or effect
the Reorganization. Piper Jaffray does not admit that it is an expert within the
meaning of the term "expert" as used in the Securities Act and the rules and
regulations promulgated thereunder, or that its opinions constitute a report or
valuation within the meaning of Section 11 of the Securities Act and the rules
and regulations promulgated thereunder.
 
     In connection with rendering its opinion, Piper Jaffray: (i) reviewed the
Reorganization Agreement; (ii) reviewed the annual reports, Forms 10-K and
audited financial statements for Michael for the three years ended December 31,
1994; (iii) reviewed the Forms 10-Q for Michael for the quarters ended March 31,
June 30 and September 30, 1995; (iv) reviewed the annual reports, Forms 10-K and
audited financial statements for NSU for the three years ended December 31,
1994; (v) reviewed the Forms 10-Q for NSU for the quarters ended March 31, June
30 and September 30, 1995; (vi) reviewed two year financial forecasts for
Michael furnished by Michael management; (vii) conducted discussions with
members of senior management of Michael; (viii) conducted discussions with
members of senior management of NSU; (ix) reviewed the historical prices and
trading activity for Michael Common Stock and NSU Common Stock; (x) reviewed the
financial terms, to the extent publicly available, of certain comparable
transactions it deemed relevant; (xi) considered the proforma effect of the
proposed Merger on Michael earnings per share for the two fiscal years ending
December 31, 1997; (xii) compared certain financial and securities data of
Michael with certain financial and securities data of companies deemed similar
to Michael or representative of the business sector in which Michael operates;
and (xiii) reviewed other financial data, performed other analyses and
considered other information as it deemed necessary and appropriate under the
circumstances.
 
     In the course of its review, Piper Jaffray relied upon and assumed the
accuracy and completeness of the financial statements and other information
provided by Michael, NSU or otherwise made available to Piper
 
                                       31

Jaffray and did not attempt independently to verify such information. Piper
Jaffray further relied upon the assurances of Michael's management that the
information provided pertaining to Michael was prepared on a reasonable basis
and, with respect to financial planning data, reflected the best currently
available estimates. In that regard, Piper Jaffray assumed, with Michael's
consent, that any projections or forecasts reflected the best currently
available estimates and judgments of the Michael management. Furthermore, Piper
Jaffray assumed that neither Michael nor NSU was a party to any pending
transaction, including external financings, recapitalizations, acquisitions or
merger discussions, other than the Merger or otherwise not in the ordinary
course of business. Piper Jaffray also assumed, with Michael's consent, that the
Merger, the Reverse Stock Split and the Distribution will not result in the
recognition of income or loss for federal income tax purposes.
 
     In arriving at its opinion, Piper Jaffray did not perform any appraisals or
valuations of specific assets of Michael or NSU and expressed no opinion
regarding the liquidation value of Michael or NSU. Its opinion is necessarily
based upon information available to it, existing facts and circumstances and
economic, market and other conditions as they exist and are subject to
evaluation on the date of the opinion. Events occurring after the date of the
opinion could materially affect the assumptions used in preparing its opinion.
Piper Jaffray expressed no opinion as to the prices at which shares of Michael
Common Stock may trade at any future time.
 
     The following is a summary of the three primary analyses performed by Piper
Jaffray in connection with its opinion.
 
     Dilution Analysis. A dilution analysis was done to determine whether the
transaction is dilutive to Michael's earnings per share. The Reorganization
Agreement contemplates that Michael will assume between $25 million and $38
million in Net Indebtedness from NSU in exchange for the retirement of a portion
of the Michael Common Stock held by NSU. The income statement effects from the
transaction are an increased level of interest expense due to the assumption of
debt and a decreased number of shares of Michael Common Stock outstanding due to
the retirement of a portion of the Michael Common Stock held by NSU. Michael's
pre-transaction earnings per share were compared to the post-transaction
earnings per share to see if and when the Reorganization was dilutive to
Michael's earnings. Piper Jaffray's analysis of those figures currently supports
the conclusion that the transaction will be accretive to New Michael earnings
per share in both fiscal 1996 and 1997.
 
     Comparable Transactions. Piper Jaffray prepared a comparable transaction
analysis to compare the discount to market to be received by Michael for the
retirement of Michael Common Stock in the Reorganization. The comparable
transaction analysis involves a review of transactions deemed comparable to the
Reorganization. Piper Jaffray focused on the following criteria to obtain a
group of such comparables: (i) privately negotiated transactions in which a
public company acquired a minority block of stock from a shareholder, excluding
open market transactions; (ii) the market capitalization of the acquiring
company exceeded $100 million; (iii) the percentage of shares repurchased was
greater than or equal to 10% but less than 50%; and (iv) the transactions
occurred between January 1, 1992, and December 21, 1995. These criteria yielded
37 transactions.
 
     Piper Jaffray then reviewed the premium or discount paid for the block of
stock at three different points: one day prior to the announcement date, one
week prior to the announcement date and four weeks prior to the announcement
date. Piper Jaffray concluded that the discount factor for the Michael Common
Stock to be retired in consideration for the retention of the Net Indebtedness
compared favorably to the mean and median discounts for the transactions it
reviewed.
 
     Cost Analysis. Piper Jaffray prepared a cost analysis that involved a
review of the costs of the Reorganization to Michael in order to determine a
range of discounts deemed appropriate for the transaction to cover such costs.
The costs Piper Jaffray analyzed included: (i) fixed costs, including all
professional fees (accountants, lawyers and financial advisors) and the costs
associated with the Michael stockholder approval process; and (ii) variable
costs, including (a) interest expense on NSU Indebtedness retained by New
Michael, after taxes; (b) incremental interest expense expected to be incurred
on Michael's current line of credit; and (c) underwriting expense for
potentially reselling the repurchased stock in a public equity underwriting. The
aggregate of these costs is dependent on the amount of debt assumed by Michael
and the
 
                                       32
<PAGE>   41
 
Michael Common Stock average per share price assumed in the redemption of
Michael Retired Shares and is currently estimated to be in the range of $2.5
million to $3.8 million.
 
     The appropriate discount to apply to the Michael Common Stock price in
order to determine the amount of shares to be repurchased in consideration for
assuming the Net Indebtedness was calculated by dividing the gross amount of the
costs (fixed plus variable) by the sum of the gross amount of the costs plus the
amount of Net Indebtedness. Based on Piper Jaffray's current analysis, the range
of implied appropriate discounts compared favorably to the discount factor
range.
 
     In addition to these primary analyses, Piper Jaffray also reviewed certain
stock market information on Michael and NSU as well as on comparable companies
to Michael. While Piper Jaffray considered these reviews to be relevant and
prudent, they did not play a major role in their determination of the fairness
of the consideration exchanged.
 
     The foregoing is a summary of the financial analyses used by Piper Jaffray
in connection with rendering its opinion. The preparation of a fairness opinion
is a complex process and is not necessarily susceptible to partial analysis or
summary description. Selecting portions of the analyses or the summary set forth
above, without considering the analyses as a whole, could create an incomplete
view of the processes underlying Piper Jaffray's opinion. In arriving at its
opinion, Piper Jaffray considered the results of all such analyses. The analyses
were prepared solely for the purposes of Piper Jaffray providing its opinion as
to the fairness of the repurchase and share exchange, from a financial point of
view, to Michael and do not purport to be appraisals or necessarily reflect the
prices at which businesses or securities actually may be sold. No company used
in the comparable company analysis summarized above is identical to Michael and
no transaction used in the comparable transaction analysis summarized above is
identical to the transactions described herein. Any analysis of the fairness of
the Merger, from a financial point of view, to Michael involves complex
considerations and judgments concerning differences in the potential financial
and operating characteristics of the comparable companies and transactions and
other factors in relation to the trading and acquisition values of the
comparable companies. Analyses based upon forecasts of future results are not
necessarily indicative of actual future results, which may be significantly more
or less favorable than those suggested by such analyses. As described above,
Piper Jaffray's opinion was one of many factors taken into consideration by the
Michael Board in making its determination to approve the Reorganization
Agreement.
 
     Michael has agreed to pay Piper Jaffray a fee of $220,000 for rendering its
financial advisory services, including its opinion. This fee was not conditioned
upon the ability of Piper Jaffray to render its opinion. Michael also agreed to
reimburse Piper Jaffray for its reasonable out-of-pocket expenses, including the
fees and disbursements of its counsel, and to indemnify Piper Jaffray against
certain liabilities, including liabilities under the federal securities laws.
 
     Opinion of NSU's Financial Advisor. NSU retained GAHS as its financial
advisor in connection with the Reorganization. As a customary part of its
investment banking business, GAHS is engaged in the valuation of businesses and
securities in connection with mergers and acquisitions, private placements, and
valuations for estate, corporate, and other purposes. GAHS does not make a
market in the NSU Common Stock or Michael Common Stock.
 
     GAHS delivered its written opinion to the NSU Board, dated as of December
21, 1995, and as of the date of this Proxy Statement/Prospectus that, based upon
and subject to the matters set forth in its written opinions, as of each such
date, the Reorganization is fair to NSU's shareholders from a financial point of
view. The full text of the written opinion of GAHS, dated as of the date of this
Proxy Statement/Prospectus, is set forth as Appendix III to this Proxy
Statement/Prospectus and describes the assumptions made, matters considered, and
limits on the review undertaken. NSU shareholders are urged to read the opinion
in its entirety. The following summary of the opinion is qualified in its
entirety by reference to the full text of the opinion attached as Appendix III
to this Proxy Statement/Prospectus. GAHS does not admit that it is an expert
within the meaning of the term "expert" as used in the Securities Act and the
rules and regulations promulgated thereunder, or that its opinions constitute a
report or valuation within the meaning of Section 11 of the Securities Act and
the rules and regulations promulgated thereunder.
 
                                       33
<PAGE>   42
 
     GAHS's opinion addresses only the fairness of the Reorganization, from a
financial point of view, to NSU's shareholders, and does not constitute a
recommendation to any NSU shareholder as to how such shareholder should vote
with respect to any of the NSU Proposals. In connection with its opinion, GAHS
was not requested to opine as to, and its opinion does not address the merits of
the basic business decision to proceed with or effect the Reorganization.
 
     In arriving at its opinion, GAHS undertook such reviews, analyses, and
inquiries as it deemed necessary and appropriate under the circumstances. Among
other things, GAHS reviewed the Reorganization Agreement, the Distribution
Agreement, and financial and other information relating to NSU and Michael. GAHS
reviewed the reported price and trading activity of NSU and Michael Common
Stock. GAHS compared certain financial and stock market information with respect
to NSU and Michael with similar information for certain other companies,
securities of which are publicly traded. GAHS made inquiries of NSU's management
as to NSU's financial condition, operating results, business outlook plans and
opportunities. GAHS also conducted discussions with members of senior management
of Michael, and reviewed all publicly available information relative to NSU and
Michael.
 
     GAHS relied upon and assumed the accuracy, completeness, and fairness of
the financial statements and other information of NSU and Michael, and did not
attempt independently to verify such information. GAHS further relied upon
assurances by NSU that the information provided to GAHS had a reasonable basis,
and with respect to projections and other business outlook information,
reflected the best currently available estimates, and that NSU was not aware of
any information or fact that would make such information provided to GAHS
incomplete or misleading.
 
     GAHS's opinion is not based on any specific appraisal of the liquidation
value of NSU or Michael or any of their respective assets, or of ENStar or any
of its assets. GAHS did not actively solicit indications of interest or value
from any third parties for NSU or any of its assets; nor did GAHS solicit
indications of interest or value from any third parties for Michael. GAHS is not
expressing any opinion as to the price at which shares of Common Stock of ENStar
or New Michael will trade subsequent to the Effective Date, and GAHS expressly
disclaims any opinion as to prices at which shares of NSU or Michael Common
Stock have traded prior to the date of the Reorganization. GAHS's opinion is
based on the information made available to it and the facts and circumstances as
they exist as of the date of such opinion, and is subject to evaluation on the
date thereof. Events occurring after the date of such opinion could materially
affect the assumptions used in preparing such opinion. GAHS was not requested to
opine, and is not opining, in any way concerning other transactions or
agreements entered into in conjunction with the Reorganization.
 
     GAHS assumed that neither NSU nor Michael was a party to any pending
transaction, including external financings, recapitalizations, acquisitions, or
merger discussions, other than the Reorganization, or in the ordinary course of
business. GAHS also assumed, based on NSU's instructions, that the
Reorganization including the Merger and the Distribution, will not result in
recognition of income or loss for federal income tax purposes.
 
     The following is a summary of the primary analysis performed by GAHS in
connection with its opinion.
 
     Economic Comparison of NSU's Alternatives for its Michael Common
Stock. Because ENStar will be configured so as to represent primarily the same
assets and liabilities currently held by NSU, with the exception of the Michael
Common Stock and the Net Indebtedness of NSU, ENStar will have the same
intrinsic value as NSU prior to the Reorganization, modified by the economic
impact of these two exceptions. Therefore, the net economic impact of the
Reorganization on NSU shareholders is measured by the financial terms of the
exchange by NSU of the Retired Michael Shares for Michael's assumption of NSU's
Net Indebtedness. GAHS's first analysis focused on a comparison of the economic
impact of this defacto sale by NSU to Michael of the Retired Michael Shares, to
other alternatives open to NSU for disposition of the Michael Shares held by
NSU.
 
          - Public Sale by NSU. GAHS analyzed and evaluated the alternatives
     available to NSU for registration of its Michael Common Stock under
     applicable federal and state securities laws, and selling such shares to
     the public through a secondary offering or in an unregistered, piecemeal
     fashion as
 
                                       34
<PAGE>   43
 
     permitted under applicable laws. GAHS concluded that such alternative would
     result in lesser after-tax proceeds and inferior intrinsic value to NSU's
     shareholders as compared to the Reorganization, due to the costs and
     expenses of such an option, including without limitation, the income taxes
     payable by NSU in conjunction with such a sale or sales, as well as other
     market issues relating to the impact of such transaction on the trading
     value of the Michael Common Stock.
 
          - Private Sale by NSU of its Michael Shares. After analysis and
     evaluation, GAHS concluded that a private sale by NSU of its Michael
     shares, without registration under applicable federal and state securities
     laws, was not practical or appropriate. Moreover, GAHS concluded that, in
     light of the tax impact of such an alternative, the intrinsic value to
     NSU's shareholders of such a private sale would be inferior to the
     Reorganization.
 
          - The Sale of Michael in its Entirety. After analysis and evaluation
     and discussions with the management of Michael and the management of NSU
     and the NSU Board, GAHS concluded that the possible sale of Michael in its
     entirety was unlikely and impractical. Such a sale, however, might result
     in a control premium and, if properly structured as a tax-free
     reorganization with respect to NSU, could result in greater value to the
     NSU shareholders than that which they may receive in the Reorganization.
     Management of Michael confirmed to GAHS, however, that it had no present
     intention to pursue such a transaction based on its belief that it would
     not be in the best interests of Michael's shareholders. Moreover, after due
     consideration and discussions with management of NSU, GAHS concluded that
     NSU was not in a position to unilaterally take action that would bring
     about a sale of Michael in its entirety without the support or initiation
     of Michael's management. A relevant consideration in GAHS's analysis was
     the requirement that any such sale of Michael in its entirety would be
     required to be structured as a tax-free reorganization with respect to NSU
     also, in order to avoid recognition of substantial taxable income by NSU so
     as to achieve an intrinsic value to NSU shareholders equal to or greater
     than the Reorganization.
 
     Comparable Transactions. GAHS prepared a comparable transaction analysis to
compare the discount to market used in determining the number of Retired Michael
Shares in the Reorganization. The comparable transaction analysis involved a
review of transactions deemed comparable to the Merger. GAHS focused on the
following criteria to determine a group of comparables: (i) privately negotiated
transactions in which a public company acquired a minority block of stock from a
shareholder, excluding open market transactions; (ii) the market capitalizations
of the acquiring company exceeded $100 million; (iii) the percentage of shares
repurchased was greater than 10% but less than 50%; and (iv) the transactions
occurred between January 1, 1992 and December 21, 1995.
 
     In addition, GAHS considered and evaluated the unique objectives and
requirements confronting buyer and seller in such comparable transactions,
including without limitation, the alternative opportunities for the seller to
dispose of the stock and the relevance of tax-free or tax-advantaged transaction
structures.
 
     GAHS then reviewed the premium or discount paid for the block of stock at
various points in time prior to and at the effective date of such transactions.
While actual discounts ranged from nominal to 40% or greater, the most
comparable transactions involved discounts in the 5% to 15% range. Key factors
in determining the appropriate discount level in such transactions include the
strength of the public market for the shares, the seller's alternatives for
divesting such shares, the redeeming company's cost of capital and financial
capability, its expenses incurred in conjunction with the stock repurchase, the
impact of the stock repurchase on the company's balance sheet and future cost of
borrowing, as well as requirements for prospective secondary offerings by the
redeeming company, and other special circumstances, including without
limitation, tax advantages and/or costs to the selling shareholder and/or the
redeeming company. Of particular relevance in GAHS's opinion, was the redemption
by E.I. DuPont de Nemours and Company of a substantial number of its shares held
by The Seagram Company Ltd. in April, 1995. The transaction highlights the
market precedence for focusing on the after-tax attributes of a redemption to
the selling company's shareholders.
 
     ENStar Strategic Considerations. GAHS considered that strategic
considerations with respect to the prospects of ENStar were not meaningfully
relevant to the issue of fairness of the Reorganization, due in large
 
                                       35
<PAGE>   44
 
measure to the fact that ENStar represents the same assets and liabilities as
NSU prior to the effective date of the Reorganization, with the exception of the
elimination of the Retired Michael Shares and the Net Indebtedness.
Nevertheless, GAHS considered that, in general, the Reorganization would have a
favorable impact on ENStar's strategic prospects for numerous reasons, including
ENStar's increased focus and decreased leverage vis-a-vis NSU.
 
     The foregoing is a summary of the analyses used by GAHS in connection with
rendering its opinion. The preparation of a fairness opinion is a complex
process and is not necessarily susceptible to partial analysis or summary
description. Selecting portions of the analyses or of the summary set forth
above, without considering the analyses as a whole, could create an incomplete
view of the processes underlying GAHS's opinion. In arriving at its opinion,
GAHS considered the results of all such analyses. The analyses were prepared
solely for the purposes of GAHS providing its opinion as to the fairness of the
Reorganization to NSU shareholders, from a financial point of view, and do not
purport to be appraisals or necessarily reflect the prices at which businesses
or securities actually may be sold. No company used in the comparable company
analyses summarized above is identical to NSU and no transaction used in the
comparable transaction analysis summarized above is identical to the
Reorganization. Any analysis of the fairness of the Reorganization to NSU
shareholders, from a financial point of view, involves complex considerations
and judgments concerning differences in the potential financial and operating
characteristics of the comparable companies and transactions and other factors
in relation to the trading and acquisition values of the comparable companies.
Analyses based upon forecasts of future results are not necessarily indicative
of actual future results, which may be significantly more or less favorable than
those suggested by such analyses. As described above, GAHS's opinion was one of
many factors taken into consideration by the NSU Board in making its
determination to approve the Reorganization.
 
     GAHS has been paid $77,500 for its financial advisory services to date,
including $25,000 in connection with the delivery of its fairness opinion on
December 21, 1995. If the Reorganization is consummated, GAHS will receive an
additional $175,000 to $225,000, depending upon the amount of the Discount
Factor, for its financial advisory services and $75,000 for the issuance of its
fairness opinion. Reasonable out-of-pocket expenses of GAHS will also be
reimbursed by NSU, and NSU has agreed to indemnify GAHS against certain
liabilities.
 
PROCEDURE FOR EXCHANGE OF CERTIFICATES
 
     General. As soon as practicable after the Effective Time, The First
National Bank of Boston, or another person mutually designated by Michael and
NSU, in its capacity as the Exchange Agent, will send a transmittal letter to
each Michael stockholder and NSU shareholder. The transmittal letter will
contain instructions with respect to the surrender of certificates representing
Michael Common Stock and NSU Common Stock in exchange for certificates
evidencing New Michael Common Stock.
 
     Michael. Upon receipt of stock certificates representing shares of Michael
Common Stock ("Michael Certificates"), the Exchange Agent will deliver shares of
New Michael Common Stock to the surrendering stockholder in accordance with the
terms of the Reorganization Agreement.
 
     If any issuance of shares of New Michael Common Stock in exchange for
shares of Michael Common Stock is to be made to a person other than the Michael
stockholder in whose name the Michael Certificate is registered at the Effective
Time, it will be a condition of such exchange that the certificate so
surrendered be properly endorsed or otherwise in proper form for transfer and
that the Michael stockholder requesting such issuance either pay any transfer or
other tax required or establish to the satisfaction of New Michael that such tax
has been paid or is not payable.
 
     After the Effective Time, there will be no further transfers of Michael
Common Stock on the stock transfer books of Michael. If a Michael Certificate
representing Michael Common Stock is presented for transfer, it will be canceled
and a certificate representing the same number of shares of New Michael Common
Stock will be issued in exchange therefor.
 
                                       36
<PAGE>   45
 
     After the Effective Time and until surrendered, shares of Michael Common
Stock will be deemed for all corporate purposes to evidence ownership of an
equal number of shares of New Michael Common Stock. New Michael will not be
obligated to deliver certificates evidencing shares of New Michael Common Stock
to former shareholders of Michael until the Michael Certificates relating to
such shares are surrendered. All declared dividends and distributions which
shall have become payable with respect to such New Michael Common Stock in
respect of a record date after the Effective Time will be paid to the holder of
record of the full shares of New Michael Common Stock regardless of whether such
holder has surrendered for exchange his or her certificates evidencing Michael
Common Stock.
 
     NSU. Upon receipt of stock certificates evidencing shares of NSU Common
Stock ("NSU Certificates"), the Exchange Agent will deliver such number of full
shares of New Michael Common Stock and cash in lieu of fractional shares of New
Michael Common Stock, if any, as such shareholder is entitled to receive after
the Reverse Stock Split, together with any dividends or other distributions of
New Michael to which such shareholder is entitled. No fractional shares of New
Michael Common Stock will be issued to NSU shareholders in connection with the
Reverse Stock Split. In lieu of issuing fractional shares, NSU shareholders will
receive cash (without interest) determined by multiplying (a) the Average Price
of Michael Common Stock times (b) the fractional share interest which such
shareholders would otherwise be entitled to receive.
 
     If any issuance of shares of New Michael Common Stock in exchange for
shares of NSU Common Stock is to be made to a person other than the NSU
shareholder in whose name the certificate is registered at the Effective Time,
it will be a condition of such exchange that the certificate so surrendered be
properly endorsed or otherwise in proper form for transfer and that the NSU
shareholder requesting such issuance either pay any transfer or other tax
required or establish to the satisfaction of New Michael that such tax has been
paid or is not payable.
 
     After the Effective Time, there will be no further transfers of pre-Reverse
Stock Split NSU Common Stock on the stock transfer books of New Michael. If a
certificate representing pre-Reverse Stock Split NSU Common Stock is presented
for transfer, it will be canceled and a certificate representing the appropriate
number of full shares of New Michael Common Stock and cash in lieu of fractional
shares and any dividends and distributions will be issued in exchange therefor.
 
     After the Effective Time and until surrendered, shares of pre-Reverse Stock
Split NSU Common Stock will be deemed for all corporate purposes, other than the
payment of dividends and distributions, to evidence ownership of the number of
full shares of New Michael Common Stock into which such NSU Common Stock was
combined in the Reverse Stock Split. No dividends or other distributions, if
any, payable to holders of NSU Common Stock will be paid to the holders of any
NSU Certificates until such certificates are surrendered. Upon surrender of such
NSU Certificates, all such declared dividends and distributions which shall have
become payable with respect to such NSU Common Stock in respect of a record date
after the Effective Time will be paid to the holder of record of the full shares
of New Michael Common Stock represented by the certificate issued in exchange
therefor, without interest.
 
DISTRIBUTION OF ENSTAR COMMON STOCK
 
     On or prior to the Effective Date of the Merger, NSU will deliver to its
transfer agent certificates representing all of the outstanding shares of ENStar
Common Stock. On the Effective Date, immediately after the Effective Time, NSU
will deliver to such transfer agent an instruction to distribute as promptly as
practicable following the Effective Date to each holder of record of NSU Common
Stock on the record date for the Distribution stock certificates evidencing one
share of ENStar Common Stock for every three shares of NSU Common Stock held of
record by such shareholder on such record date for the Distribution and cash in
lieu of any fractional shares of ENStar Common Stock. No certificate or scrip
representing fractional shares of ENStar Common Stock will be issued as part of
the Distribution, and in lieu of receiving fractional shares each holder of NSU
Common Stock who would otherwise be entitled to receive a fractional share of
ENStar Common Stock pursuant to the Distribution will receive cash for such
fractional share. NSU will instruct its transfer agent to determine the number
of whole shares and fractional shares of ENStar Common Stock
 
                                       37
<PAGE>   46
 
allocable to each holder of record of NSU Common Stock as of the record date for
Distribution, to aggregate all such fractional shares into whole shares and sell
the whole shares obtained thereby in the open market, if possible, at then
prevailing prices on behalf of the holders who otherwise would be entitled to
receive fractional share interests and to distribute to each such holder such
holder's ratable share of the total proceeds of such sale. ENStar will bear the
costs and commissions incurred in connection with such sale. If the transfer
agent is unable to sell such shares in the open market, ENStar will pay to such
holders, in lieu of any fractional share, an amount of cash determined by
multiplying (a) the average closing price per share of ENStar Common Stock on
the Nasdaq National Market during the five days following the Effective Date
times (b) the fractional share interest to which such holder would otherwise be
entitled.
 
LOST, STOLEN OR DESTROYED CERTIFICATES
 
     In the event any Michael Certificates or NSU Certificates have been lost,
stolen or destroyed, the Exchange Agent will issue shares of New Michael Common
Stock, in exchange for such lost, stolen or destroyed certificates upon the
making of an affidavit of that fact by the owner of such certificates, provided
that New Michael may, in its discretion require the holder of such lost, stolen
or destroyed certificates to deliver a bond in a reasonable sum as indemnity
against any claim that may be made against New Michael or the Exchange Agent
with respect to the certificates alleged to have been lost, stolen or destroyed.
 
DETAILED INSTRUCTIONS, INCLUDING A TRANSMITTAL LETTER, WILL BE MAILED TO MICHAEL
STOCKHOLDERS AND NSU SHAREHOLDERS PROMPTLY FOLLOWING THE EFFECTIVE TIME AS TO
THE METHOD OF EXCHANGING CERTIFICATES FORMERLY REPRESENTING SHARES OF MICHAEL
AND NSU COMMON STOCK. MICHAEL STOCKHOLDERS AND NSU SHAREHOLDERS SHOULD NOT SEND
CERTIFICATES REPRESENTING THEIR SHARES TO THE EXCHANGE AGENT PRIOR TO RECEIPT OF
THE TRANSMITTAL LETTER.
 
ESCHEAT AND WITHHOLDING
 
     NSU, Merger Co., New Michael and ENStar will not be liable to any holder of
NSU Common Stock or Michael Common Stock for any consideration due such holder
as a part of the Reorganization delivered to a public official pursuant to any
applicable abandoned property, escheat or similar law. New Michael or the
Exchange Agent will be entitled to deduct and withhold from such consideration
to any NSU shareholder such amounts as New Michael or the Exchange Agent is
required to deduct and withhold with respect to the making of such payment under
any provision of federal, state, local or foreign tax law.
 
INTEREST OF CERTAIN PERSONS IN THE REORGANIZATION
 
     In considering the respective recommendations of the Michael Board and the
NSU Board regarding the Reorganization Agreement and the transactions
contemplated thereby, stockholders of Michael and shareholders of NSU should be
aware that certain members of the management of Michael and NSU and the Michael
and the NSU Boards have certain interests in the Reorganization that may be
different from, or in addition to, the interests of stockholders of Michael and
shareholders of NSU generally.
 
     Michael. All of the current directors of Michael, except James H. Michael
and Orville L. Freeman, will become directors of New Michael. In addition, the
executive officers of Michael will become executive officers of New Michael. See
"THE REORGANIZATION AGREEMENT -- New Michael Management Following the
Reorganization."
 
     Pursuant to the Reorganization Agreement, New Michael will assume all
existing Michael stock option plans and the stock award portion of Michael's
Executive Incentive Plan. At the Effective Time, each outstanding right to
purchase shares of Michael Common Stock (a "Michael Option"), will be assumed by
New Michael in such manner that it is converted into an option to purchase the
same number of shares of New Michael Common Stock at the same exercise price.
Each Michael Option assumed by New Michael will have the same terms and
conditions as then are applicable to such Michael Option. As of April 15, 1996,
directors and executive officers of Michael held outstanding Michael Options to
purchase             shares of Michael Common Stock at exercise prices ranging
from             .

     NSU. At or prior to the Effective Time, all of the NSU stock options
outstanding under the NSU stock option plans will be canceled or exercised and
all NSU stock option plans will terminate.
 
     Concurrently with the execution of the Reorganization Agreement, the
Michael Family Shareholders, who own an aggregate of 5,685,100 shares (or
approximately 60%) of the outstanding Common Stock of NSU, entered into the
Orderly Disposition Agreement. Under the Orderly Disposition Agreement, the
Michael Family Shareholders have agreed until the Effective Time (i) not to
sell, offer to sell, hypothecate or transfer any shares of NSU, unless sold
pursuant to Rule 144 of the Securities and Exchange Commission, pledged to
secure certain surety bonds or transferred among the Michael Family
Shareholders, (ii) to cause NSU to vote in favor of the Merger, the Reverse
Stock Split, the Distribution and the election of directors nominated by the New
Michael Board of Directors at any meeting of New Michael shareholders called for
such purpose, and (iii) prepare any necessary pre-merger notifications as
required under the HSR Act. The Michael Family Shareholders have also agreed to
refrain for a period of two years following the Effective Date from selling,
pledging or otherwise disposing of (i) shares of New Michael Common Stock
exceeding 5% of the outstanding shares of New Michael Common Stock, or (ii) any
of their shares to a purchaser who owns or would own more than 5% of the
outstanding New Michael Common Stock without giving an option to New Michael to
purchase such shares, except that they may pledge shares to secure certain
surety bonds. New Michael must exercise its option by completing the purchase of
the shares within twenty days of notification by the Michael Family Shareholders
of an intent to sell. The restrictions do not apply if a tender offer is made
for all of the outstanding New Michael Common Stock unless management of New
Michael announces opposition to the tender offer. In addition, the Michael
Family Shareholders are entitled during such two year period to certain
piggyback registration rights under the Act with respect to the New Michael
Common Stock if New Michael proposes to register common stock under the Act. The
Michael Family Shareholders also are entitled up to two times, during such two
year period, to request registration of a minimum of 500,000 shares for sale in
a public offering. However, New Michael would not be obligated to register
shares if registration required a special audit and New Michael may delay the
registration for 120 days under certain circumstances. Each selling Michael
Family Shareholder will pay New Michael a pro rata share of the registration
expenses, the aggregate fees and disbursements of underwriters, underwriting
discounts and commissions and transfer taxes, if any, and fees and disbursements
of counsel to the Michael Family Shareholders in connection with any
registration.
 
     Finally, for a period of two years following the Effective Time, the
Michael Family Shareholders will be entitled to nominate two directors to the
New Michael Board if they collectively own ten percent or more of the
outstanding common stock of New Michael and one director to the Board if their
ownership is below ten percent. The initial designees of the Michael Family
Shareholders to the New Michael Board are Jeffrey J. Michael and Miles E. Efron,
both of whom currently are Michael directors. A copy of the Orderly Disposition
Agreement is attached hereto as Exhibit E to the Reorganization Agreement
included in Appendix I.
 
     Peter E. Flynn, Executive Vice President, Chief Financial Officer and
Secretary of NSU, is a party to an employment agreement with NSU and Transition
which terminates December 31, 1997. Pursuant to that agreement, if Mr. Flynn's
employment is terminated due to a "change in control" of NSU, Mr. Flynn is
entitled to receive a single lump sum payment of $297,000. Also, if Mr. Flynn is
terminated by NSU, all of his then outstanding options immediately become
vested. The consummation of the Reorganization will result in such a change in
control under the terms of that agreement and Mr. Flynn's employment with NSU
will be terminated.
 
ACCOUNTING TREATMENT
 
     The Merger will be accounted for as a business combination utilizing the
reverse acquisition method with Michael being the acquiror for accounting
purposes under generally accepted accounting principles. As such, the Merger
will be treated as an acquisition using the purchase method of accounting with
no change in the recorded amount of Michael's assets and liabilities. The assets
and liabilities of NSU that are acquired as a result of the Merger will be
recorded at their fair market values. The ENStar assets and liabilities will be
recorded at their historic amounts, as recorded in the books and records of NSU,
following the Distribution.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     Consummation of the Reorganization is conditional upon receiving the
following rulings from the IRS:
 
          The Merger. The Merger will qualify as a reorganization within the
     meaning of Section 368(a)(1)(B) of the Code and NSU and Michael will each
     be a party to the reorganization within the meaning of Section 368(b) of
     the Code. Accordingly: (i) no income, gain or loss will be recognized by
     NSU or Michael as a result of the consummation of the Merger; (ii) no gain
     or loss will be recognized by the holders of Michael Common Stock upon the
     exchange of Michael Common Stock solely for New Michael Common Stock
     pursuant to the Merger; (iii) the basis of the New Michael Common Stock
     received by a stockholder of Michael pursuant to the Merger will be the
     same as the basis of the Michael Common Stock surrendered in exchange
     therefor; and (iv) the holding period of the New Michael Common Stock
     received by a stockholder of Michael pursuant to the Merger will include
     the period during which the Michael Common Stock surrendered therefor was
     held, provided the Michael Common Stock is a capital asset in the hands of
     the stockholder of Michael at the time of the Merger.
 
          The Reverse Stock Split. The Reverse Stock Split will not be treated
     as a stock distribution, or a transaction that has the effect of such a
     distribution, to which Sections 301, 305(b) or 305(c) of the Code apply.
     Accordingly, no taxable income will be recognized under such Sections by
     any of the shareholders of NSU except for cash paid in lieu of fractional
     shares, which cash payment shall be treated as received by the holder of
     NSU Common Stock as a distribution in redemption of the fractional share
     interest and such shareholder will recognize gain or loss, subject to the
     provisions and limitations of Section 302 of the Code.
 
          The Distribution. The Distribution will qualify as a tax-free
     distribution under Sections 355 and 368(a)(1)(D) of the Code. Accordingly:
     (i) NSU shareholders will not recognize income, gain or loss upon the
     receipt of ENStar Common Stock; (ii) the tax basis of the shares of ENStar
     Common Stock and New Michael Common Stock (including any fractional share
     interests to which an NSU shareholder is entitled) held by an NSU
     shareholder after the Distribution will be the same as the tax basis of the
     shares of NSU Common Stock held by such shareholder immediately before the
     Distribution, allocated in proportion to the fair market values of the
     shares of ENStar Common Stock and New Michael Common Stock on the
     Distribution Date; (iii) the holding period for the shares of ENStar Common
     Stock received by the NSU shareholders will include the holding period of
     the shares of NSU Common Stock with respect to which the Distribution was
     made, provided that the shares of NSU Common Stock are held as a capital
     asset on the Distribution Date; and (iv) where cash is received by a holder
     of NSU Common Stock pursuant to the Distribution in lieu of fractional
     share interests in NSU Common Stock, the cash payment will be treated as
     received by the holder of NSU Common Stock as a distribution in redemption
     of the fractional share interest and such shareholder will recognize gain
     or loss, subject to the provisions and limitations of Section 302 of the
     Code.
 
     Treasury regulations governing Section 355 of the Code require that each
NSU shareholder who receives shares of ENStar Common Stock pursuant to the
Distribution attach a statement to the federal income tax return that will be
filed by the shareholder for the taxable year in which such shareholder received
the shares of ENStar Common Stock, which statement shows the applicability of
Section 355 of the Code to the Distribution. ENStar has represented that it will
provide each ENStar shareholder with information necessary to comply with this
requirement.
 
     The rulings described above will be based upon certain representations,
including representations that (i) the holders of Michael Common Stock do not
have any plan or intention to sell, exchange or otherwise dispose of a number of
shares of New Michael Common Stock received pursuant to the Merger that would
reduce the ownership of New Michael Common Stock by all of the pre-Merger
holders of Michael Common Stock to a number of shares having a value, as of the
date of the Merger, of less than 50% of the value of all of the formerly
outstanding Michael Common Stock as of the same date and (ii) the holders of
ENStar Common Stock do not have any plan or intention to sell, exchange or
otherwise dispose of any of their ENStar or New Michael Common Stock following
and as part of the Distribution.
 
                                       40
<PAGE>   49
 
     Where cash is received by a holder of NSU Common Stock who exercises
dissenters' rights in connection with the Distribution, the cash payment will be
treated as received by the holder of NSU Common Stock as a distribution in
redemption of such shareholder's NSU Common Stock and such shareholder will
recognize gain or loss, subject to the provisions and limitations of Section 302
of the Code.
 
     The foregoing is only a general description of certain anticipated federal
income tax consequences of the Merger, Reverse Stock Split, and Distribution
without regard to the particular facts and circumstances of the tax situation of
each stockholder of Michael or shareholder of NSU. It does not discuss all of
the consequences that may be relevant to Michael's stockholders or NSU's
shareholders entitled to special treatment under the Code (such as insurance
companies, dealers in securities, exempt organizations or foreign persons) or to
shareholders of NSU or stockholders of Michael who acquired their NSU Common
Stock or Michael Common Stock pursuant to the exercise of employee stock options
or otherwise as compensation. The summary set forth above does not purport to be
a complete analysis of all potential tax effects of the transactions
contemplated by the Reorganization Agreement or the Merger itself or the
Distribution Agreement or the Distribution itself. No information is provided
herein with respect to the tax consequences, if any, of the Merger, Reverse
Stock Split or Distribution under state, local or foreign tax laws.
 
THIS FEDERAL INCOME TAX DISCUSSION IS FOR GENERAL INFORMATION ONLY AND MAY NOT
APPLY TO ALL HOLDERS OF NSU COMMON STOCK OR TO ALL HOLDERS OF MICHAEL COMMON
STOCK. SUCH HOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO THE
SPECIFIC TAX CONSEQUENCES OF THE REORGANIZATION.
 
REGULATORY APPROVALS
 
     Antitrust. Under the HSR Act and the rules and regulations thereunder, the
Reorganization may not be consummated until notifications have been given and
certain information has been furnished to the Antitrust Division of the United
States Department of Justice (the "Antitrust Division") and the FTC and
specified waiting period requirements have been satisfied. NSU and Michael each
filed with the Antitrust Division and the FTC a Notification and Report Form
(the "Notification and Report Form") with respect to the Merger on
               . The initial waiting period for each of these filings is
scheduled to expire at 11:59 p.m. on                , unless Michael's and NSU's
request for early termination is granted.
 
LISTING OF NEW MICHAEL COMMON STOCK; DIVIDENDS
 
     New Michael expects to continue the Nasdaq National Market listing of NSU
Common Stock, but will use the symbol MIKL, rather than NSRU, and will
discontinue the listing of New Michael Common Stock on the Pacific Stock
Exchange. The payment of future dividends on New Michael Common Stock will be a
business decision to be made by the New Michael Board from time to time based
upon the results of operations and financial condition of New Michael and such
other factors as the New Michael Board considers relevant.
 
LISTING OF ENSTAR COMMON STOCK; DIVIDENDS
 
     ENStar has applied to have the ENStar Common Stock approved for quotation
on the Nasdaq National Market under the symbol "ENSR." Since ENStar will not
have been publicly traded prior to the Distribution, there can be no assurance
that an active market will develop or be sustained after the Distribution,
although NSU has been advised that certain market makers in NSU Common Stock
expect to make a market in ENStar Common Stock. Management of ENStar currently
intends to retain any earnings for use in its operations and does not anticipate
paying any cash dividends in the foreseeable future.
 
EFFECT ON STOCK OPTION PLANS
 
     The 1987 Incentive Stock Option Plan of Michael, the 1987 Non-Qualified
Stock Option Plan of Michael, the 1992 Stock Option Plan for Non-Employee
Directors of Michael, the 1994 Executive Incentive Plan, and the 1994 Executive
Performance Share Award Plan (the "Michael Stock Plans") and the Michael Options
will be assumed and adopted by New Michael in accordance with the terms of the
Michael Stock
 
                                       41
<PAGE>   50
 
Plans and the Michael Options, and will have the rights provided in such plans,
which will remain unaffected by the Merger. New Michael will reserve a
sufficient number of authorized but unissued shares of New Michael Common Stock
for issuance under the Michael Stock Plans. As required pursuant to the terms of
the Reorganization Agreement, all outstanding NSU stock options will be
exercised or canceled by the Effective Date and all NSU stock option plans will
be terminated.
 
FEDERAL SECURITIES LAWS CONSEQUENCES
 
     All shares of New Michael Common Stock received by Michael stockholders and
NSU shareholders in the Merger, and all shares of ENStar Common Stock received
by NSU shareholders in the Distribution, will be freely transferable, except
that shares of New Michael Common Stock received by persons who are deemed to be
"affiliates" (as such term is defined under the Securities Act), of Michael or
NSU prior to the Merger and shares of ENStar Common Stock received by persons
who are deemed to be "affiliates" of NSU or ENStar may be resold by them only in
transactions permitted by the resale provisions of Rule 145 promulgated under
the Securities Act (or Rule 144 in the case of such persons who become
affiliates of New Michael or ENStar) or as otherwise permitted under the
Securities Act. Persons who may be deemed to be affiliates of Michael, NSU,
ENStar or New Michael generally include individuals or entities that control,
are controlled by, or are under common control with, such party and may include
certain officers and directors of such party as well as principal stockholders
of such party.
 
DISSENTERS' RIGHTS
 
     Under the Delaware General Corporation Law (the "DGCL"), holders of Michael
Common Stock are not entitled to dissenters' rights in connection with the
Merger because the Michael Common Stock is designated as a national market
system security on an interdealer quotation system by Nasdaq, Inc., and the
consideration which such holders will receive in the Merger consists solely of
New Michael Common Stock, which will also be designated as a national market
system security on an interdealer quotation system by Nasdaq, Inc.
 
     Holders of NSU Common Stock who do not vote in favor of the Distribution
and who have properly complied with Sections 302A.471 and 302A.473 of the MBCA
will be entitled to dissenters' rights. Under the Reorganization Agreement, NSU
is not required to complete the Merger if holders of 1% or more of the
outstanding NSU Common Stock effectively elect dissenters' rights.
 
     Shareholders of NSU that follow the procedures set forth in Section
302A.473 will be entitled to have their shares of NSU Common Stock appraised by
a Minnesota court and to receive payment of the "fair value" of such shares as
determined by that court. The shares of NSU Common Stock with respect to which
the holder has perfected a demand for dissenters' rights in accordance with
Section 302A.473 and has not effectively withdrawn or lost his rights to such
appraisal are referred to in this Proxy Statement/Prospectus as the "Dissenting
Shares."
 
     Section 302A.473 entitles any holder of the NSU Common Stock who objects to
the Distribution, in lieu of receiving securities to which he or she would be
entitled to under the Reorganization Agreement and the Distribution Agreement,
to dissent therefrom and obtain payment for the "fair value" of his or her
shares of NSU Common Stock. Any shareholder of NSU contemplating the exercise of
these dissenters' rights should carefully review the provisions of Sections
302A.473 of the MBCA which has been provided as Appendix IV to this Proxy
Statement/Prospectus, particularly the specific procedural steps to perfect such
rights. SUCH RIGHTS WILL BE LOST IF THE PROCEDURAL REQUIREMENTS OF SECTION
302A.473 ARE NOT FULLY AND PRECISELY SATISFIED.
 
     Set forth below (to be read in conjunction with the full text of Section
302A.473 included with this Proxy Statement/Prospectus) is a brief description
of the procedures relating to the exercise of dissenters' rights. The following
description does not purport to be a complete statement of the provisions of
Section 302A.473 and is qualified in its entirety by reference thereto.
 
                                       42
<PAGE>   51
 
     Under Section 302A.473, Subd. 3, a shareholder of NSU who wishes to
exercise dissenters' rights (a "Dissenter") must file with NSU at Suite 610,
Park National Bank Building, 5353 Wayzata Blvd., Minneapolis, Minnesota 55416
before the vote on the NSU Proposals, a written notice of intent to demand the
"fair value" of NSU Common Stock owned by such shareholder. A shareholder of NSU
may not assert dissenters' rights as to less than all of the shares registered
in the name of such shareholder unless that shareholder dissents with respect to
all the shares that are beneficially owned by another person but registered in
the name of such shareholder and discloses the name and address of each
beneficial owner on whose behalf such shareholder dissents. In that event, the
rights of the Dissenter shall be determined as if the shares as to which such
shareholder dissented and the other shares were registered in the names of
different shareholders. A beneficial owner of shares of NSU Common Stock who is
not the record holder may assert dissenters' rights with respect to shares held
on behalf of the beneficial owner, and shall be treated as a Dissenter, if the
beneficial owner submits to NSU a written consent of the record holder of such
shares. IN ADDITION, THE SHAREHOLDER MUST NOT VOTE HIS OR HER SHARES IN FAVOR OF
THE DISTRIBUTION. A VOTE AGAINST SUCH PROPOSAL WILL NOT IN ITSELF CONSTITUTE
SUCH A WRITTEN NOTICE AND A FAILURE TO VOTE WILL NOT AFFECT THE VALIDITY OF A
TIMELY WRITTEN NOTICE. HOWEVER, THE SUBMISSION OF A BLANK PROXY WILL CONSTITUTE
A VOTE IN FAVOR OF SUCH PROPOSAL AND A WAIVER OF STATUTORY DISSENTERS' RIGHTS.
 
     If the Distribution is approved by the shareholders of NSU, New Michael
will send to all Dissenters who file the necessary notice of intent to demand
the fair value of their shares and who did not vote their shares in favor of
such proposals, a notice containing certain information required by Section
302A.473, Subd. 4, including without limitation the address to which a Dissenter
must send a demand for payment and certificates representing shares in order to
obtain payment for such shares and the date by which they must be received. In
order to receive the fair value of the shares under Section 302A.473, a
Dissenter must demand payment and deposit certificates representing shares of
NSU Common Stock within 30 days after such notice from New Michael is given.
Under Minnesota law, notice by mail is given by New Michael when deposited in
the United States mail. A SHAREHOLDER WHO FAILS TO MAKE DEMAND FOR PAYMENT AND
TO DEPOSIT CERTIFICATES AS REQUIRED BY SECTION 302A.473, SUBD. 4, WILL LOSE THE
RIGHT TO RECEIVE THE FAIR VALUE OF HIS OR HER SHARES UNDER SUCH SECTION
NOTWITHSTANDING THE TIMELY FILING OF NOTICE OF INTENT TO DEMAND PAYMENT UNDER
SECTION 302A.473, SUBD. 3.
 
     Except as provided below, if demand for payment and deposit of stock
certificates is duly made by a Dissenter with New Michael as required by the
notice, then after the Effective Time or the receipt of the demand, whichever is
later, New Michael will pay the Dissenter an amount that New Michael estimates
to be the fair value of the Dissenter's shares of NSU Common Stock, with
interest, if any. Under Sections 302A.471 and 302A.473, "fair value" means the
value of the shares of NSU Common Stock immediately before the Effective Time
and "interest" means interest commencing five days after the Effective Date
until the time of payment, calculated at the rate provided in Minnesota Statutes
Section 549.09. If the Dissenter believes the payment received from New Michael
is less than the fair value of the shares of NSU Common Stock, with interest, if
any, such Dissenter must give written notice to New Michael of his or her own
estimate of the fair value of the shares of NSU Common Stock, with interest, if
any, within 30 days after the date of New Michael's remittance, and must demand
payment of the difference between his or her estimate and New Michael's
remittance. If the Dissenter fails to give written notice of such estimate to
New Michael within the 30-day time period, such Dissenter will be entitled only
to the amount remitted by New Michael.
 
     New Michael may withhold such remittance with respect to shares of NSU
Common Stock for which the Dissenter demanding payment (or persons on whose
behalf such Dissenter acts) was not the beneficial owner as of December 21,
1995, the first public announcement date of the Merger (the "Public Announcement
Date"). As to each Dissenter who has validly demanded payment, following the
Effective Time or the receipt of demand, whichever is later, New Michael will
mail its estimate of the fair market value of such Dissenter's shares of NSU
Common Stock and offer to pay this amount with interest, if any, to the
Dissenter upon receipt of such Dissenter's agreement to accept this amount in
full satisfaction. If such Dissenter believes
 
                                       43
<PAGE>   52
 
that New Michael's offer is less than the fair value of the shares of NSU Common
Stock, with interest, if any, such Dissenter must give written notice to New
Michael of his or her own estimate of the fair value of the shares of NSU Common
Stock with interest, if any, and demand payment of this amount. This demand must
be mailed to New Michael within 30 days after the mailing of New Michael's
offer. If the Dissenter fails to make this demand within such 30 day time
period, such Dissenter shall be entitled only to the amount offered by New
Michael.
 
     If New Michael and the Dissenter cannot reach a settlement within 60 days
after New Michael receives the Dissenter's estimate of the fair value of his or
her shares of NSU Common Stock, then New Michael must file a petition in the
district court of Hennepin County, Minnesota, requesting that the court
determine the statutory fair value of the NSU Common Stock, with interest, if
any. All Dissenters whose demands are not settled within the applicable 60-day
settlement period will be made parties to this proceeding.
 
     The court will then determine whether each Dissenter in question has fully
complied with the provisions of Section 302A.473, and for all Dissenters who
have fully complied and not forfeited statutory dissenters' rights, will
determine the fair value of the Dissenters' shares, taking into account any and
all factors the court finds relevant (including, without limitation, the
recommendation of any appraisers that may have been appointed by the court),
computed by any method that the court, in its discretion, sees fit to use,
whether or not used by New Michael or a Dissenter. The fair value of the
Dissenters' shares as determined by the court is binding on all shareholders and
may be less than, equal to or greater than the consideration to the holders if
the Reorganization is completed. However, under the statute, Dissenters are not
liable to New Michael for the amount, if any, by which payments remitted to the
Dissenters exceed the fair value of such shares determined by the court, with
interest. The costs and expenses of this court proceeding will be assessed
against New Michael, except that the court may assess part or all of such costs
and expenses against a Dissenter whose action in demanding payment is found to
be arbitrary, vexatious or not in good faith.
 
     Under Section 302A.471, Subd. 4, a shareholder of NSU has no right at law
or equity to set aside the consummation of the Merger, the Reverse Stock Split,
the Distribution or the New Articles, unless the adoption thereof is fraudulent
with respect to such shareholder or NSU.
 
     FAILURE TO FOLLOW THE STEPS REQUIRED BY SECTION 302A.473 FOR PERFECTING
DISSENTERS' RIGHTS MAY RESULT IN THE LOSS OF SUCH RIGHTS. IN VIEW OF THE
COMPLEXITY OF THE PROVISIONS OF SECTION 302A.473, SHAREHOLDERS OF NSU WHO ARE
CONSIDERING DISSENTING FROM THE DISTRIBUTION SHOULD CONSULT THEIR OWN LEGAL
ADVISORS.
 
     NSU shareholders considering exercising dissenters' rights should bear in
mind that the fair value of their NSU Common Stock determined under Section
302A.473 could be more than, the same as or less than the value of the
consideration they will receive pursuant to the Reorganization Agreement if they
do not exercise dissenters' rights. In addition, in most cases, NSU shareholders
who receive cash for the fair value of their shares of NSU Common Stock upon the
exercise of dissenters' rights will realize taxable gain or loss for federal
income tax purposes. EACH SHAREHOLDER OF NSU IS URGED TO CONSULT WITH HIS OR HER
OWN PERSONAL TAX AND FINANCIAL ADVISORS CONCERNING FEDERAL INCOME TAX
CONSEQUENCES OF THE EXERCISE OF DISSENTERS' RIGHTS, AS WELL AS ANY APPLICABLE
STATE, LOCAL, FOREIGN OR OTHER TAX CONSEQUENCES, BASED UPON SUCH SHAREHOLDER'S
OWN PARTICULAR FACTS AND CIRCUMSTANCES.
 
                          THE REORGANIZATION AGREEMENT
 
     The following information describes certain aspects of the Reorganization
Agreement. This description does not purport to be complete and is qualified in
its entirety by reference to the Appendices hereto, including the Reorganization
Agreement and exhibits thereto, which are attached to this Proxy
Statement/Prospectus as Appendix I and are incorporated herein by reference. All
stockholders are urged to read Appendix I in its entirety. See also "THE
DISTRIBUTION AGREEMENT."
 
GENERAL
 
     The Reorganization Agreement provides that: (i) Merger Co. will be merged
with and into Michael and Michael will become a wholly-owned subsidiary of NSU;
(ii) in the Merger, each stockholder of Michael
 
                                       44
<PAGE>   53
 
(other than NSU) will receive, in exchange for each share of Michael Common
Stock held by such stockholder, one share of New Michael Common Stock; (iii) NSU
will change its name to Michael Foods, Inc. and will continue the business
previously conducted by Michael (Michael will change its name to Michael Foods
of Delaware, Inc.); (iv) prior to the consummation of the Merger, NSU will
transfer to ENStar all of its assets and liabilities other than certain
indebtedness and cash, as determined by NSU and other agreed upon assets and
liabilities; (v) the outstanding common stock of ENStar will, conditioned upon
the consummation of the Merger, be distributed pro rata to the shareholders of
NSU of record as of a record date just prior to the Effective Date; and (vi)
immediately prior to the Effective Time, NSU will effectuate the Reverse Stock
Split. The ratio of the Reverse Stock Split will be determined pursuant to the
terms of the Reorganization Agreement in the manner described below. See also
"THE REORGANIZATION -- Effects of the Reorganization."
 
EFFECTS OF THE REORGANIZATION ON THE STOCKHOLDERS OF MICHAEL AND THE
SHAREHOLDERS OF NSU
 
     Michael Stockholders. Upon consummation of the Merger, each outstanding
share of Michael Common Stock, other than the Michael Common Stock owned by NSU,
will be converted into the right to receive one share of New Michael Common
Stock.
 
     On and after the Effective Date, and until surrendered for exchange, each
outstanding stock certificate which immediately prior to the Effective Time
represented shares of Michael Common Stock will be deemed for all purposes to
evidence ownership of and to represent the same number of whole shares of New
Michael Common Stock and the record holder of such outstanding certificate will,
after the Effective Date, be entitled to vote the shares of New Michael Common
Stock into which such shares of Michael Common Stock will have been converted on
any matters on which the holders of record of the New Michael Common Stock, as
of any date subsequent to the Effective Date, are entitled to vote. In any
matters relating to such certificates of Michael Common Stock, New Michael may
rely conclusively upon the record of stockholders maintained by Michael or its
agent containing the names and addresses of the holders of record of Michael
Common Stock on the Effective Time.
 
     NSU Shareholders. On the Effective Date, immediately prior to the Effective
Time, but in any event subject to the consummation of the Merger, NSU will
effectuate the Reverse Stock Split. In the Reverse Stock Split, each outstanding
share of NSU Common Stock will be converted into a fraction of one share of New
Michael Common Stock determined by multiplying each such share by a fraction
where the denominator is the number of outstanding shares of NSU Common Stock
immediately prior to the Effective Date and the numerator is the number of
shares of Michael Common Stock owned by NSU at such date less the Retired
Michael Shares. For purposes of the Reorganization Agreement, Net Indebtedness
is defined to be the amount of outstanding NSU subordinated debentures and fixed
or extendible time certificates and the Dissenting Shares Holdback less cash
retained by New Michael. The Dissenting Shares Holdback is an amount to be
mutually agreed upon by NSU and Michael based on the number of Dissenting
Shares. Under the terms of the Reorganization Agreement, the Net Indebtedness
retained by New Michael may not be less than $25,000,000 nor more than
$38,000,000. The number of shares of Michael Common Stock to be retired in
consideration for the Net Indebtedness will be determined by dividing the amount
of Net Indebtedness by the Average Price of Michael Common Stock after applying
a certain percentage discount to the Average Price of Michael Common Stock. The
Discount Factor will be based upon the amount of Net Indebtedness, ranging from
92% at $25,000,000 to 90% beginning at $33,750,000, resulting in an effective
discount of between 8% and 10%. The Discount Factor is determined pursuant to
Exhibit A to the Reorganization Agreement, a copy of which is included in
Appendix I to this Proxy Statement/Prospectus.
 
     Pursuant to the Distribution Agreement between NSU and ENStar, prior to the
Merger, NSU will contribute and transfer to ENStar, all of NSU's assets, other
than: (i) such amount of cash as NSU may, in its sole discretion, determine to
retain at the Effective Date; (ii) 7,354,950 shares of Michael Common Stock
owned by NSU; (iii) the capital stock of Merger Co.; (iv) the rights of NSU
under the Reorganization Agreement, the Distribution Agreement and the Orderly
Disposition Agreement; and (v) all net operating loss carryforwards and other
tax attributes properly allocable to NSU following the Effective Date in
accordance with the relevant provisions of the Code (the "NSU Retained Assets").
ENStar also will assume
 
                                       45
<PAGE>   54
 
all NSU liabilities other than: (i) liabilities arising from assertion of
dissenters' rights by NSU shareholders, (ii) liabilities under the
Reorganization Agreement, the Distribution Agreement or the Orderly Disposition
Agreement; and (iii) NSU's indebtedness (including principal and accrued
interest, the "NSU Indebtedness") represented by NSU's outstanding subordinated
debentures, subordinated extendible time certificates, subordinated fixed time
certificates and bank debt (collectively, the "NSU Assumed Liabilities"). In
addition, with certain limited exceptions, all intercompany receivables,
payables and loans in existence as of the Effective Time between NSU and any NSU
subsidiary, will be eliminated, without the transfer of cash, by dividend or
capital contributions, as appropriate.
 
     On or prior to the Effective Date, NSU will deliver to its transfer agent
certificates representing all of the outstanding shares of ENStar Common Stock.
On the Effective Date, immediately after the Effective Time, NSU will deliver to
such transfer agent an instruction to distribute as promptly as practicable
following the Effective Date to each holder of record of NSU Common Stock on the
record date for the Distribution stock certificates evidencing one share of
ENStar Common Stock for every three shares of NSU Common Stock held of record by
such shareholder on such record date for the Distribution and cash in lieu of
any fractional shares of ENStar Common Stock. No certificate or scrip
representing fractional shares of ENStar Common Stock will be issued as part of
the Distribution, and in lieu of receiving fractional shares each holder of NSU
Common Stock who would otherwise be entitled to receive a fractional share of
ENStar Common Stock pursuant to the Distribution will receive cash for such
fractional share.
 
NEW MICHAEL MANAGEMENT FOLLOWING THE REORGANIZATION
 
     The Board of Directors of New Michael (the "New Michael Board") after the
Merger will consist of nine members, seven of whom will be designated by the
Michael Board. These designees are expected to include Gregg A. Ostrander,

Common Stock to be issued in the Reorganization under state blue sky laws to the
extent such qualification is necessary.
 
     In the event the Reorganization Agreement is properly terminated: (i) by
Michael or NSU due to the failure of NSU to obtain the requisite shareholder
approval for the NSU Proposals; (ii) by Michael due to the failure by NSU to
satisfy certain conditions or if any of NSU's warranties and representations are
not true and correct and the failure to be true and correct would have a
material adverse effect on NSU; (iii) by NSU if the Average Price of Michael
Common Stock is less than $11.00 per share; (iv) by Michael if a representation
or warranty given by NSU in the Reorganization Agreement is updated in such a
way that the information indicates that NSU has suffered or will suffer a
material adverse effect, or in the case of NSU's representation in the
Reorganization Agreement regarding NSU's liabilities as of the Effective Time,
Michael determines that NSU has suffered or will suffer a material liability,
which has not been cured within 15 days after notice to NSU of Michael's intent
to terminate because of the updated information; or (v) by NSU if holders of in
excess of 1% of the outstanding NSU Common Stock effectively exercise
dissenters' rights, then, within ten days after written demand from Michael, NSU
will pay to Michael an amount equal to the out of pocket expenses incurred by
Michael in connection with the transactions contemplated by the Reorganization
Agreement, up to an aggregate of $500,000, payable either, at the option of NSU,
in cash or in shares of Michael Common Stock having a fair market value
(determined on the basis of the average closing sales price of Michael Common
Stock during the twenty trading days immediately preceding such termination)
equal to such amount.
 
     In the event the Reorganization Agreement is terminated (i) by Michael or
NSU due to the failure of Michael to obtain the requisite stockholder approval
for the Reorganization Agreement and the Merger; (ii) by NSU due to the failure
of Michael to satisfy certain conditions or, if any of Michael's warranties and
representations are not true and correct, and the failure to be true and correct
would have a material adverse effect on Michael; (iii) by Michael if the Average
Price of Michael Common Stock is more than $17.00 per share; (iv) by NSU after
notice to Michael and an opportunity to cure if a representation or warranty
given by Michael in the Reorganization Agreement is updated in such a way that
the information indicates that Michael has suffered or will suffer a material
adverse effect or material liability; or (v) the transactions contemplated by
this Agreement are not consummated solely because Michael has not obtained the
necessary modifications to its material debt instruments or prepaid such debt
instruments, then, within ten days after written demand from NSU, Michael must
pay to NSU an amount equal to the out of pocket expenses incurred by NSU in
connection with the transactions contemplated by this Agreement, up to an
aggregate of $500,000, payable either in cash, or in shares of Michael Common
Stock having a fair market value (determined on the basis of the average closing
sales price of Michael Common Stock during the twenty trading days immediately
preceding such termination) equal to such amount.
 
     The expense reimbursement provisions in the Reorganization Agreement are
the sole and exclusive remedies of Michael and NSU for any termination of the
Reorganization Agreement.

<PAGE>   58
 
GENERAL
 
     The Reorganization Agreement provides that NSU will, and will cause ENStar
to, execute and deliver the Distribution Agreement prior to the Effective Date.
The Distribution Agreement requires NSU to contribute and transfer to ENStar or
a ENStar subsidiary, as appropriate, all of NSU's assets (the "NSU Transferred
Assets"), except for the NSU Retained Assets. In addition, ENStar will assume
all liabilities of NSU (i) arising at any time prior to the Merger Effective
Date, other than the NSU Assumed Liabilities, or (ii) arising as a result of the
Distribution other than the NSU Assumed Liabilities (the NSU Transferred
Liabilities"). With certain limited exceptions, all intercompany receivables,
payables and loans between NSU and any NSU subsidiary in existence as of the
Effective Date will be eliminated.
 
     In the Distribution Agreement, ENStar acknowledges that NSU is not
representing or warranting in any way (i) as to the value or freedom from
encumbrance of, or any other matter concerning, any NSU Transferred Assets or
(ii) as to the legal sufficiency to convey title to any such assets or the
execution and delivery of the Distribution Agreement. All such assets are being
transferred as is, where is, and ENStar will bear all economic and legal risks
with respect to the NSU Transferred Assets.
 
CONDITIONS
 
     The Distribution is expressly conditioned on the prior consummation of the
Merger. The Distribution will not occur (i) if, on the Effective Date, NSU has
not received an opinion of tax counsel or a private letter ruling from the IRS
to the effect that the Distribution will qualify as a tax-free spin-off under
Section 355 of the Code, and (ii) unless prior to such time the following
conditions have been satisfied or waived: (a) the transfer of the NSU
Transferred Assets to and the assumption of the NSU Transferred Liabilities by
ENStar has been completed, (b) the ENStar Common Stock has been approved for
quotation on the Nasdaq National Market or listing on a national securities
exchange, (c) the ENStar Board has been elected by NSU, as sole shareholder of
ENStar; (d) the ENStar Registration Statement has been declared effective by the
Commission and the Form 8-A relating to the shares of ENStar Common Stock to be
distributed in the Distribution has become effective under the Exchange Act; and
(e) all conditions precedent to the obligations of NSU and Michael under the
Reorganization Agreement (other than consummation of the Distribution) will have
been satisfied or waived and the Merger has been consummated.
 
THE DISTRIBUTION
 
     On or prior to the Effective Date, NSU will deliver to its transfer agent
certificates representing all of the outstanding shares of ENStar Common Stock.
On the Effective Date, immediately after the Effective Time, NSU will deliver to
such transfer agent an instruction to distribute as promptly as practicable
following the Effective Date to each holder of record of NSU Common Stock on the
record date for the Distribution stock certificates evidencing one share of
ENStar Common Stock for every three shares of NSU Common Stock held of record by
such shareholder on such record date for the Distribution and cash in lieu of
any fractional shares of ENStar Common Stock. No certificate or scrip
representing fractional shares of ENStar Common Stock will be issued as part of
the Distribution, and in lieu of receiving fractional shares each such holder of
NSU Common Stock pursuant to the Distribution will receive cash for such
fractional share. If the number of outstanding shares of ENStar Common Stock
exceeds the amount to be distributed in the Distribution, then the remaining
shares will be deemed to have been contributed by NSU to the capital of ENStar
and retired and canceled. All of the shares of ENStar Common Stock issued in the
Distribution will be fully paid, nonassessable and free of preemptive rights.
 
CERTAIN COVENANTS
 
     The Distribution Agreement provides that New Michael will not, nor will it
permit Michael to do any of the following during the two year period following
the Effective Date: (i) liquidate Michael; (ii) merge Michael with or into
another corporation, unless Michael is the surviving corporation and the merger
is not treated for tax purposes as a sale or other disposition of Michael Common
Stock; (iii) sell any shares of Michael Common Stock or cause Michael to issue
any shares of Michael Common Stock to any party other
 
                                       50
<PAGE>   59
 
than NSU; or (iv) sell any assets of New Michael to any third party not
otherwise an affiliate of the foregoing, except for (a) sales in the ordinary
course of business or (b) sales of assets if, after giving effect to such sales,
Michael will retain at least 90% of the fair market value of its gross assets in
active trades or businesses within the meaning of Section 355 of the Code;
provided, however, New Michael or Michael may undertake any of the actions
listed above if (1) ENStar consents thereto or (2) New Michael obtains either a
tax opinion or a favorable private letter ruling from the IRS, in each case
reasonably satisfactory to ENStar, to the effect that the actions to be
undertaken would not adversely affect the tax free nature of the Merger or the
Distribution to all of the parties thereto. The shareholders of record of NSU on
the record date for the Distribution are third party beneficiaries of the
foregoing restrictions.
 
     ENStar and NSU have agreed in the Distribution Agreement that, on or prior
to the Distribution Date, to the extent required under any indenture with
respect to any of the outstanding debentures or any of the outstanding
subordinated extendible or fixed time certificates of NSU, they will execute and
deliver supplemental indentures or other agreements or instruments evidencing
ENStar's assumption of NSU's obligations with respect to such outstanding
debentures and subordinated extendible and fixed time certificates; provided,
however, that as between NSU and ENStar, the NSU Indebtedness is not considered
an NSU Transferred Liability and New Michael, after the Effective Time, shall be
responsible for the payment in full, in accordance with the terms thereof of all
of the NSU Indebtedness and shall indemnify ENStar for any and all liabilities
with respect to the NSU Indebtedness.
 
INDEMNIFICATION
 
     From and after the Effective Date, ENStar will indemnify New Michael,
Michael and all Michael subsidiaries and Merger Co. against: (i) all liabilities
(other than the NSU Assumed Liabilities) of NSU or any NSU subsidiary (other
than Michael and its Subsidiaries), including any subsidiary owned by NSU prior
to the Effective Date but not owned by NSU on the Merger Effective Date, arising
out of: (a) the NSU Transferred Liabilities, and (b) the transactions
contemplated under the Distribution Agreement, including the Distribution and
any taxes as a result of the Distribution (other than (X) any liabilities
resulting from any breach by New Michael, after the Effective Date, of the
Distribution Agreement, (Y) any liability of NSU for taxes resulting from a
breach by New Michael of the restrictions set forth above relating to the two
year period after the Effective Date, and (Z) obligations, after the Effective
Date, expressly assumed by New Michael under the Distribution Agreement); (ii)
all liabilities arising from any claim made by any shareholder of ENStar on or
after the Effective Date or by any shareholder or former shareholder of NSU
prior to the Effective Date relating to any act or omission of NSU on or prior
to the Effective Date in connection with the Merger or any of the other
transactions as contemplated by the Reorganization Agreement; (iii) all
liabilities assumed by ENStar in the Distribution Agreement relating to the
employee benefit plans of NSU; (iv) all liabilities of ENStar or any subsidiary
of ENStar arising out of transactions or events entered into or occurring after
the Effective Date, or any action or inaction, including but not limited to,
contracts, commitments and litigation, with respect to, entered into or based
upon transactions or events occurring after the Effective Date with respect to
ENStar or any subsidiary of ENStar (other than the NSU Assumed Liabilities); (v)
any breach of the Distribution Agreement by ENStar or any subsidiary of ENStar
after the Effective Date; and (vi) damages, costs, and expenses including
attorney's fees incurred in defending and settling claims for such liabilities.
 
     From and after the Effective Date, New Michael will indemnify ENStar and
any ENStar subsidiary against: (i) all liabilities of New Michael, Michael or
any subsidiary of New Michael or Michael arising out of transactions or events
entered into or occurring after the Effective Date, or any action or inaction,
including but not limited to, contracts, commitments and litigation, with
respect to, entered into or based upon transactions or events occurring after
the Effective Date with respect to New Michael, Michael, any subsidiary of New
Michael after the Effective Date or any subsidiary of Michael, other than any
liability arising out of the NSU Transferred Liabilities; (ii) all liabilities
relating to the NSU Assumed Liabilities; (iii) all liabilities of Michael or any
subsidiary of Michael arising before, on or after the Merger Effective Date;
(iv) all liabilities arising from any claim made by any current or former
Michael stockholder or shareholder of New Michael after the Effective Date who
was a Michael stockholder or NSU shareholder immediately prior to the
 
                                       51
<PAGE>   60
 
Effective Date relating to any act or omission of Michael in connection with the
Merger or any of the other transactions contemplated in the Reorganization
Agreement or the Distribution Agreement; (v) any breach of the Distribution
Agreement by New Michael after the Merger Effective Date; and (vi) damages,
costs and expenses including attorney's fees incurred in defending and settling
claims for such obligations, expenses or liabilities.
 
     The Distribution Agreement provides for certain procedures for the parties
to assert claims for indemnification thereunder, including the mediation and
arbitration of disputes arising under the Distribution Agreement. In the event
that New Michael realizes a benefit in the form of a reduction in the federal or
state income taxes which New Michael would otherwise be obligated to pay, as a
result of the net operating loss carryforwards properly allocable to New Michael
from all tax periods prior to or ending on the Effective Date, ENStar has the
right to set-off the amount of any such tax savings against any liability of
ENStar under the Distribution Agreement (including the indemnification
obligations described above).
 
     In order to provide for the required payments to be made to satisfy
Dissenters' claims, New Michael will retain cash in an amount to be agreed upon,
in excess of the cash applied to NSU's indebtedness. Any cash not used for this
purpose will be delivered to ENStar after payment of all Dissenters' claims.
ENStar also is required to pay or cause the release of New Michael from certain
obligations of NSU under certain leases and NSU's guarantee of indebtedness of a
subsidiary of NSU within three years after the Effective Date (the date of the
release of such obligations, the "Release Date").
 
     In order to further provide that ENStar will be able to meet its
indemnification obligations to New Michael under the Distribution Agreement,
ENStar has agreed in the Distribution Agreement that it will not: (i) pay any
dividends, whether in cash or in property, or make any other distribution to its
shareholders, or redeem any of its capital stock for cash or property; (ii)
sell, transfer or dispose of any material amount of its assets in a single
transaction or related series of transactions, except in the ordinary course of
its business or for fair value; or (iii) sell, transfer or dispose of all or
substantially all of its assets or engage in any merger, consolidation or
reorganization unless (a) in the case of the sale, transfer or other disposition
of all or substantially all of its assets, the purchaser assumes the obligations
of ENStar (jointly and severally with ENStar) under the Distribution Agreement,
(b) in the case of a merger, consolidation or reorganization, the surviving
entity assumes the obligations of ENStar under the Distribution Agreement, or
(c) the Market Value (as defined below) of ENStar immediately after giving
effect to such dividend, distribution, redemption or other transaction is at
least equal to the following amounts during the following periods: (X)
$9,000,000 during the period beginning on the Effective Date and continuing to
the later to occur of (a) the Release Date or (b) the third anniversary of the
Effective Date; (Y) $3,000,000 during the period from the end of the period
referenced in clause (X) above and continuing to the fifth anniversary of the
Effective Date. The term "Market Value" is defined in the Distribution Agreement
as the greater of: (a) the market capitalization of ENStar's outstanding equity
securities, if ENStar is a publicly traded company, or (b) the net book value of
ENStar computed in accordance with generally accepted accounting principles,
except that securities owned by ENStar which are publicly traded shall be valued
at their market value without any adjustment for lack of liquidity or control
premium, but reduced for any taxes payable on the disposition of such
securities, taking into account any and all tax benefits available to ENStar and
using ENStar's then applicable effective tax rate for purposes of such
calculations.
 
     Under the Distribution Agreement, New Michael is required to repay in full
all of the NSU Indebtedness not later than six months after the Effective Date.
All such repayments (excluding any payments made with respect to any instruments
that have matured or otherwise become due and payable in accordance with their
respective terms prior to such repayment date) are to be effected on or about
the same date.

          UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS
 
     The following Unaudited Pro Forma Condensed Combined Financial Statements
are prepared to give effect to the consummation of the Reorganization. The
Reorganization contemplates that prior to the Effective Date, NSU will transfer
certain of its assets, including its investment in CorVel, and certain of its
liabilities, other than certain indebtedness, to ENStar. The combined historical
net assets and results of the entities that NSU will contribute to ENStar are
contained in the columns labeled ENStar Historical.
 
     The pro forma balance sheet and pro forma statements of earnings of NSU
give effect to the Distribution as if the Distribution had occurred at December
31, 1995 and January 1, 1995, respectively. The unaudited pro forma condensed
combined balance sheet and unaudited condensed combined pro forma statement of
earnings of New Michael have been prepared as if the Reorganization was
consummated on December 31, 1995 and January 1, 1995, respectively.
 
     Assumptions underlying the pro forma adjustments are described in the
accompanying notes which should be read in conjunction with these pro forma
statements. These statements should be read in conjunction with the historical
financial statements of NSU, Michael, ENStar and CorVel, and the notes thereto,
which are incorporated by reference herein. The pro forma statements do not
purport to be indicative of the actual results of operations which would have
occurred had the Reorganization been consummated at the beginning of the period,
or of the future results of operations which may be obtained by ENStar or New
Michael.

                   NOTES TO THE UNAUDITED PRO FORMA CONDENSED
                         COMBINED FINANCIAL STATEMENTS
 
A.  To record the January 1996 sale of 350,000 shares of CorVel common stock by
    NSU for $11,050,000, to recognize the related gain which will be offset
    against existing net operating loss carryforwards and to eliminate the
    related deferred income tax liability. These proceeds ($11,050,000),
    together with the cash and cash equivalents of NSU ($3,123,000), are then
    applied to eliminate a portion of long-term debt and all current maturities
    of NSU.
 
B.  To reflect the reacquisition of 2,560,594 Retired Michael Shares and the
    assumption of Net Indebtedness of $27,061,000. See "THE
    REORGANIZATION -- Effects of the Reorganization" for an example of such
    calculation. This entry also eliminates NSU's current equity in Michael, the
    related deferred income taxes and the gain recognized on the sale of the
    CorVel common stock.
 
C.  To apply fair value purchase accounting to the Net Indebtedness acquired by
    New Michael as a part of the Merger. The Net Indebtedness has an effective
    interest rate of approximately 10% and is assumed to be retired and replaced
    with indebtedness having an effective interest rate of approximately 7% six
    months after the Merger. See footnotes F and G below.
 
D.  To reclassify deferred transaction costs of Michael related to the
    Reorganization as additional cost of the Retired Michael Shares.
 
E.  To eliminate NSU's nonrecurring corporate general and administrative
    expenses of $249,000 and to reflect reduced compensation levels at ENStar by
    $200,000. NSU's continuing costs are the costs of administering the Net
    Indebtedness retained by New Michael.
 
F.  To record the amortization of the fair market value adjustment recorded by
    Michael related to the Net Indebtedness retained by New Michael. (See
    footnote C above.)
 
G.  To adjust interest expense related to the Net Indebtedness retained by New
    Michael assuming such indebtedness, net of the cash acquired, is retired and
    replaced with indebtedness having an effective interest rate of
    approximately 7% for the last six months of the year.
 
H.  To adjust income tax expense based on the effective income tax rate for
    Michael for the year ended December 31, 1995.
 
I.  To eliminate NSU's equity in earnings in unconsolidated subsidiaries for
    Michael and the portion attributable to the CorVel common stock sold in
    January 1996.
 
J.  To reduce the number of shares of Michael Common Stock outstanding to
    reflect the Retired Michael Shares. The number of Retired Michael Shares was
    computed based on the calculations set forth herein under "THE
    REORGANIZATION -- Effect of the Reorganization."
 
K.  To reflect the pro forma income per share of ENStar utilizing the weighted
    average number of shares of NSU Common Stock outstanding for the year ended
    December 31, 1995. The calculation assumes one share of ENStar will be
    distributed for every three shares of NSU Common Stock.

                    DESCRIPTION OF NEW MICHAEL CAPITAL STOCK
 
     Upon adoption of the New Articles by the shareholders of NSU, New Michael's
authorized capital stock will consist of 50,000,000 shares: 40,000,000 shares of
Common Stock, par value $.01 per share, and 10,000,000 shares of undesignated
stock. The following description assumes that the New Articles have been adopted
by the shareholders of NSU.
 
COMMON STOCK
 
     The holders of the Common Stock of New Michael are entitled to receive
ratably such dividends, if any, as may be declared by the New Michael Board out
of funds legally available for the payment of dividends, after provision for
payment of preferred stock dividends, if any. In all matters to come before the
shareholders, holders of the New Michael Common Stock will be entitled to one
vote for each share of New Michael Common Stock held and are not entitled to
cumulate votes, which means that the holders of a majority of the total voting
power of such shares can elect all of the directors entitled to be elected by
the holders of New Michael Common Stock. Shareholders will have no preemptive
rights. In the event of the liquidation, dissolution or winding up of New
Michael, subject to the preferential rights, if any, of preferred shareholders,
the holders of New Michael Common Stock are entitled to share ratably in all
assets of New Michael remaining after provision for payment of liabilities. The
outstanding shares of NSU Common Stock are, and the shares of New Michael Common
Stock to be issued in the Reorganization, when issued as described herein, will
be validly issued, fully paid and nonassessable.
 
UNDESIGNATED STOCK
 
     Pursuant to the New Articles, the New Michael Board is authorized, without
shareholder approval, to issue one or more classes or series of stock with
respect to which the New Michael Board may determine voting, conversion and
other rights which could adversely affect the rights of holders of New Michael
Common Stock. The rights of the holders of New Michael Common Stock generally
would be subject to the prior rights of any preferred stock with respect to
dividends, liquidation preferences and other matters. Among other things,
preferred stock could be issued by New Michael to raise capital or to finance
acquisitions. The issuance of preferred stock under certain circumstances could
have the effect of delaying or preventing a change of control of New Michael.
 
TRANSFER AGENT AND REGISTRAR
 
     The First National Bank of Boston is the Transfer Agent for the Michael
Common Stock and will be appointed as the transfer agent for the New Michael
Common Stock.
 
BUSINESS COMBINATION STATUTE AND CONTROL SHARE ACQUISITION ACT
 
     New Michael will be governed by the provisions of Sections 301A.671 and
302A.673 of the MBCA, which may deny shareholders the receipt of a premium for
their stock in the case of certain unfriendly acquisitions and which may also
have a depressive effect on the market price of New Michael's Common Stock. In
general, Section 302A.671 provides that the shares of a corporation acquired in
a "control share acquisition" have no voting rights unless voting rights are
approved in a prescribed manner. A "control share acquisition" is an
acquisition, directly or indirectly, of beneficial ownership of shares that
would, when added to all other shares beneficially owned by the acquiring
person, entitle the acquiring person to have voting power of 20% or more in the
election of directors. In general, Section 302A.673 prohibits a public Minnesota
corporation from engaging in a "business combination" with an "interested
shareholder" for a period of four years after the date of the transaction in
which the person became an interested shareholder, unless the business
combination is approved in a prescribed manner. "Business combination" includes
mergers, asset sales and other transactions resulting in a financial benefit to
the interested shareholder. An "interested shareholder" is a person who is the
beneficial owner, directly or indirectly, of 10% or more of the corporation's
voting stock or who is an affiliate or associate of the corporation and at any
time within four years prior to the
 
                                       58
<PAGE>   67
 
date in question was the beneficial owner, directly or indirectly, of 10% or
more of the corporation's voting stock.
 
TAKEOVER OFFERS
 
     Minnesota Statute sec. 80B.01 et seq. (the "Takeover Act") requires
registration of any takeover offer of a company which is an issuer of publicly
traded equity securities (i) which (a) has its principal place of business or
its principal executive office located in Minnesota, or (b) owns or controls
assets located in Minnesota which have a fair market value of at least
$1,000,000, and (ii) which (a) has more than ten percent of its beneficial or
record equity security holders resident in Minnesota, (b) has more than ten
percent of its equity securities owned beneficially or of record by residents in
Minnesota, or (c) has more than 1,000 beneficial or record equity security
holders resident in Minnesota. A takeover offer is an offer to acquire any
equity securities of the described companies from a resident of Minnesota
pursuant to a tender offer or request or invitation for tenders, if after the
acquisition of all securities acquired pursuant to the offer either (i) the
offeror would be directly or indirectly a beneficial owner of more than ten
percent of any class of the outstanding equity securities of the target company
and was directly or indirectly the beneficial owner of less than ten percent of
any class of the outstanding equity securities of the target company prior to
the commencement of the offer; or (ii) the beneficial ownership by the offeror
of any class of the outstanding equity securities of the target company would be
increased by more than ten percent of that class and the offeror was directly or
indirectly the beneficial owner of ten percent or more of any class of the
outstanding equity securities of the target company prior to the commencement of
the offer. A takeover offer does not include: (a) An offer in connection with
the acquisition of a security which, together with all other acquisitions by the
offeror of securities of the same class of equity securities of the issuer,
would not result in the offeror having acquired more than two percent of such
class during the preceding 12-month period; (b) an offer by the issuer to
acquire its own equity securities unless the offer is made during the pendency
of a takeover offer by a person who is not an associate or affiliate of the
issuer; or (c) an offer in which the target company is an insurance company
subject to regulation by the Minnesota Commissioner of Commerce, a financial
institution regulated by the Minnesota Commissioner of Commerce, or a public
service utility subject to regulation by the public utilities commission.
Certain limitations exist which provide that the offer must be made on
substantially the same terms inside and outside the state. The offeree has
certain rights to withdraw securities tendered and the Takeover Act provides
penalties for failure to comply with any provision of the Takeover Act of up to
$25,000 and/or up to 5 years in prison. Shares acquired in violation of the Act
are nontransferable and are denied voting rights for one year after acquisition.
New Michael can call the shares for redemption at the price that the shares were
acquired. Any seller who sells to an offeror who violates the Takeover Act can
sue, subject to the limitations period, in law or in equity, and may sue for
rescission.
 
                               BUSINESS OF ENSTAR
 
     ENStar was formed on December 20, 1995, as a wholly owned subsidiary of
NSU, and has had no operations and held no assets. Prior to the Effective Date,
pursuant to the terms of the Distribution Agreement, NSU will transfer all of
its assets and liabilities to ENStar, except the capital stock of Merger Co.,
all of the shares of Michael Common Stock that it holds, certain of its
outstanding indebtedness and a certain amount of cash, to be determined in the
discretion of NSU. The date of such transfer is hereinafter referred to as the
"Asset Transfer Date."
 
     At the time of the Distribution, ENStar's operations will consist of the
operations of its direct and indirect operating companies, which consist of
Americable, Inc. ("Americable") and Transition Networks, Inc. ("Transition"). In
addition, at April 15, 1996, NSU owned 1,225,000 shares of the common stock,
$.0001 par value, of CorVel (the "CorVel Common Stock"), which represents
approximately 27% of the outstanding shares of CorVel Common Stock . The CorVel
Common Stock is traded on the Nasdaq National Market under the Symbol CRVL. The
closing price per share of the CorVel Common Stock on April 15, 1996 was
$       . All of the shares of CorVel Common Stock held by NSU on the Asset
Transfer Date will be contributed to ENStar. NSU may, prior to the Asset
Transfer Date, sell from time to time some of its CorVel Common Stock pursuant
to Rule 144 of the Securities Act; however, it presently does not intend to sell
more
 
                                       59
<PAGE>   68
 
than 50,000 shares. Proceeds from any such sale or sales would be retained by
NSU to reduce the amount of Net Indebtedness to be assumed by New Michael in the
Reorganization. ENStar contemplates that it will directly employ seven
management and administrative employees.
 
UNCONSOLIDATED SUBSIDIARY
 
     CorVel. Since its initial public offering in June 1991, CorVel has been
operated as an independent company. As a less-than-majority-owned subsidiary of
NSU, CorVel's operations have not been consolidated with NSU, and NSU's
investment in CorVel is accounted for under the equity method of accounting.
ENStar will account for its investment in CorVel in the same manner. The
following summary of CorVel's business has been prepared from information
reported by CorVel. Additional information regarding CorVel is available from
the reports and other documents prepared and filed by CorVel with the Securities
and Exchange Commission.
 
     CorVel is an independent nationwide provider of medical cost containment
and managed care services designed to address escalating medical costs. CorVel's
services include preferred provider organizations, automated medical fee
auditing, medical case management, independent medical examinations, utilization
review and vocational rehabilitation services. Such services are provided to
insurance companies, third party administrators and employers to assist them in
managing the medical costs and monitoring the quality of care associated with
medical claims.
 
     Since its initial public offering in June 1991, Jeffrey J. Michael and
Peter E. Flynn, each directors of NSU, have been members of the Board of
Directors of CorVel. Notwithstanding the sale by NSU of 350,000 shares of its
CorVel Common Stock in January 1996, and the corresponding reduction in NSU's
percentage ownership in CorVel from approximately 35% to 27%, it is expected
that Messrs. Michael and Flynn will continue to serve as members of the CorVel
Board of Directors and be nominated for re-election to the CorVel Board at the
next annual meeting of stockholders of CorVel. There are no agreements, however,
between NSU and CorVel or any of CorVel's stockholders requiring the nomination
of Messrs. Michael and Flynn or any designees of NSU for election as directors
of CorVel. NSU also does not have any agreement with CorVel requiring CorVel to
register the shares of CorVel Common Stock held by NSU. At NSU's request in
December 1995, CorVel agreed to register the 350,000 shares of CorVel Common
Stock that were sold in 1996. In the absence of registration of its CorVel
Common Stock, ENStar's ability to sell the CorVel Common Stock will be limited
to sales pursuant to Rule 144 of the Securities Act, and the volume limitations
thereof, and to private negotiated sales, which may adversely affect the ability
of ENStar to sell a large portion of its CorVel Common Stock at a given time.
 
OPERATING SUBSIDIARIES
 
GENERAL
 
     Americable. Americable was organized as a Minnesota corporation in 1981 and
was acquired by NSU in December 1986. Americable is a provider of networking and
connectivity products and services used in providing solutions for customers
operating a wide range of data communications systems. Americable has organized

PC and networking needs.
 
                                       60
<PAGE>   69
 
     As a distributor, Americable supplies a wide array of voice and data
communication related products such as cable (both copper and fiber optic),
cable assemblies, components (blocks, jacks, connectors, patch cords, patch
panels) and networking hardware. The principal focus of Americable's
distribution business, conducted primarily through its National Distribution
Sales division in Minneapolis, Minnesota, is to provide quality products, prompt
reliable delivery of such products and strong customer service both before and
after the products are sold. Americable sells to a wide range of customers
throughout the United States in the voice and data communications aftermarket,
including resellers, other distributors, systems integrators, installers and
end-users.
 
     Through Americable Custom Products, Americable manufactures a wide variety
of cable assemblies, sub-assemblies and specialty products for its customers.
While some of these products are manufactured to standard specifications for
sale by Americable through its distribution business, most are custom designed
and manufactured by Americable to customer specifications. These customer
designed products are manufactured for both end-users and original equipment
manufacturers ("OEMs").
 
     Transition. Transition develops, manufactures, markets and supports a broad
line of data networking hardware products that provide physical connectivity for
LANs and mini- and mainframe networks. Physical connectivity devices enable
computing and other electronic devices to communicate over a LAN. These devices
include high-speed switches, managed and unmanaged hubs, transceivers, media
converters and other related networking devices.
 
     Transition's products include intelligent hubs and switches, passive and
active terminal network products, including baluns, media converters and
transceivers, unmanaged Ethernet and Token Ring hubs and related host modules,
multi-port multi-media repeaters, network adapter cards and other passive
devices. Transition sells its products to a number of volume distributors and
VAR's throughout the United States and certain countries world-wide. The
customers that purchase Transition products through its network of distributors
and VAR's include system integrators, installers and end-users.
 
INDUSTRY
 
     A growing number of organizations are reengineering their businesses and
are using PC-based network technology to enhance productivity. PC networks
increase speed and flexibility, provide improved functionality to end-users and
provide greater productivity, often at lower costs. The growth in demand for
personal computers, along with recent advances in networking technology, have
led to an increase in demand for interconnected LANs and WANs. Such networks
facilitate efficient and rapid data communications among connected work groups
and departments providing for more effective utilization of information and
computing resources. As LANs have proliferated, demand for multi-vendor
interoperability has led to industry standard network protocols and access
methods such as Ethernet and Token-Ring.
 
     More recently there has been an increasing demand to connect users of LANs
in other geographic areas using WANs. Applications such as on-line services,
electronic mail, sharing of databases, multi-site product development and
transaction processing are leading the demand for the inter-networking of LANs
and WANs. The integration of LANs and WANs requires data communication products
which efficiently, reliably and quickly transmit data to appropriate locations.
 
     In the face of this rapidly changing technological environment, the
decision-making process that organizations face when planning, selecting and
implementing information technology solutions is growing more complex.
Organizations must select from numerous product options with shortening life
cycles. Although networks enhance business productivity, they typically present
complex management problems and increased administrative costs. Thus, many
organizations find it increasingly difficult and costly to maintain the internal
infrastructure needed to support their networks. As a result of these trends,
companies increasingly seek to outsource the management and support of their PC
network infrastructure.
 
     It is estimated that in 1995 the overall market in the United States for
networking products and services was approximately $50 billion.

BUSINESS STRATEGY
 
     Americable. Americable's objective is to be a leading provider of a
complete range of network products and services to medium to large sized
enterprises throughout the United States. To meet this goal, Americable believes
it must seek to maintain its current customer relationships and continually
expand its customer base in the regions in which it operates, continue to
develop strong relationships with its key suppliers, look for opportunities to
expand its branch locations and develop and enhance its value-added service
offerings.
 
     During 1995, approximately 5,200 customers purchased products or services
from Americable. Management at Americable believes that preserving and enhancing
these relationships is a constant priority. Continuous quality improvement in
its operations along with expansion and enhancement of its product and service
offerings are some of the means that Americable utilizes to enhance its customer
relationships.
 
     Management at Americable also believes that developing strong relationships
with the leading manufacturers of networking products allows Americable to offer
its customers name brand products that provide the best value in meeting their
networking needs. Americable has developed relationships with leading
manufacturers within each of its principal product lines, such as Bay Networks,
Inc., AMP Incorporated and Berk-Tek Inc. and seeks to add new relationships to
expand its value-added service capabilities. Americable believes that utilizing
a select range of suppliers allows it to provide superior customer service
because its technical personnel are more familiar with the products sold and
because such high quality products are generally more reliable. Further, such
strong relationships result in greater continuity of product supply.
 
     From 1991 to 1995, Americable's domestic sales have increased from $27.6
million to $42.2 million. This increase in sales has been generated through
internal growth at Americable's four principal locations in Atlanta, Chicago,
Dallas and Minneapolis, primarily as a result of the addition of new sales,
engineering and technical personnel. Also during 1995, Americable opened smaller
satellite offices in Milwaukee, Wisconsin and Fargo, North Dakota. Americable
plans to continue its growth strategy through the addition of new sales,
engineering and technical personnel in both existing locations and new
geographic markets. Americable also intends to look for opportunities to acquire
businesses in the same or related industries in an effort to expand
geographically or enhance its value-added service offerings.
 
     Since 1989, Americable has made substantial investments in the development
of its value-added networking capabilities primarily through the addition of
engineering and technical personnel. During 1995, Americable introduced a number
of service offerings designed to provide its customers with customized
integrated solutions to meet their unique network computing needs. Revenues from
technical services and installation in 1995 represented 7% of Americable's total
revenues. Americable believes there are opportunities to increase Americable's
overall gross margins by increasing the volume of services that it currently
offers to its customers and intends to focus on increasing its service revenues.
 
     Transition. The market for Transition's products is characterized by rapid
technological change, constantly evolving industry standards and rigorous
competition with respect to timely product innovation. Because the introduction
of products embodying new technology and the emergence of new industry standards
can render existing products obsolete and unmarketable, Transition believes that
its future success will depend upon its ability to develop, manufacture and
market new products and enhancements to existing products on a cost-effective
and timely basis. Transition seeks to identify niche market opportunities for
new or enhanced products and quickly respond by offering a new or enhanced
product that may have greater capabilities, better functionability or
flexibility, greater ease of use or equivalent capabilities or functionability
but a lower price point than other competitive products.
 
     As LANs have proliferated, demand for multi-vendor interoperability has led
to industry standard network protocols and access methods such as Ethernet,
Token-Ring and Fiber Distributed Data Interface ("FDDI"). Transition has
developed the majority of its LAN products using industry standards, primarily
Ethernet. Ethernet's cabling media has evolved from coaxial cable to its
associated 10BaseTL fiber optic cabling. Management at Transition believes that
the LAN/WAN products market will continue to be driven by the migration of
end-users to new applications that demand more speed and flexibility.
Accordingly,
 
                                       62
<PAGE>   71
 
Transition's research and development efforts have been targeted at high speed
(100Mbs+) LANs and the integration of LANs and WANs into a single platform.

      response for problem resolution, "spare-in-the-air" hardware replacement
      and cabling system diagnosis and repair. In addition, Americable offers
      several fixed price service offerings for preventative maintenance such as
      CASE (Cable Analysis Service) and EASE (Enterprise Analysis Service).
 
     Americable is committed to providing networking products, services and
systems to customers of all sizes in the geographic areas served by its four
principal regional offices. Sales from the Americable Network Technologies
division constituted approximately 74% of Americable's net sales in 1995. In
addition to supported distribution sales, Americable Network Technologies will
oversee the design and implementation of projects involving multiple LANs across
a wide area network, consisting of multi-vendor hardware products and several
thousand nodes. Value-added projects generally range in size from $10,000 to
$500,000. During 1995, sales derived from value-added projects and services
consisted of approximately 18% of Americable's net sales. Value-added projects
and services sales include sales of products such as bulk cable, cable
assemblies and networking devices and services such as training, installation
and maintenance.
 
     The National Distribution Sales Division
 
     Through its distribution business, operated principally through the
National Distribution Sales division, Americable maintains a wide variety of
high-quality products in its inventory (over 5,000). Product inventory ranges
from connectivity products such as bulk cable, connectors, patch panels, racks
and other cable accessories to more complex networking electronic devices such
as concentrators, hubs, switches and routers. As a distributor, Americable
generally inventories products from multiple manufacturers. Principal
manufacturers of connectivity products include Berk-Tek, Inc., Amp Incorporated,
General Cable Corp., The Siemens Company and Leviton Manufacturing, Inc. In
addition, in an effort to reduce its inventory levels, Americable purchases a
number of networking products through large distributors such as Tech Data
Corporation, Gates/Arrow and Ingram Micro, Inc.
 
     Americable also maintains an integrated, real-time, on-line computerized
system for order entry, fulfillment and inventory control. This on-line computer
system allows sales personnel to advise customers over the phone of product
specifications, availability and order status. All orders are normally shipped
within 24 hours of receipt and, when necessary, can be shipped on a "same-day"
basis.
 
     The National Distribution Sales division seeks to add value for its
customers by providing superior customer service. All of Americable's sales
representatives and other sales and marketing personnel are trained to assist
customers in product selection, implementation and system upgrading and
expansion. The division's sales representatives are supported by the technical
staff of the Americable Network Technologies division, who have a broad range of
expertise in various networking technologies.
 
     The National Distribution Sales division services customers of all sizes in
the voice and data communications aftermarket. Customer orders range in size
from under $50 to several hundred thousand dollars. Average order size of the
division during 1995 was approximately $600. The distribution business of
Americable (including sales of cable assemblies) constituted approximately 26%
of Americable's net sales in 1995.
 
     Americable Custom Products
 
     As a natural extension of its distribution business, and consistent with
Americable's marketing strategy to be a single-source provider for its
customers, the Americable Custom Products division provides a manufacturing
capability to satisfy the individual needs of those customers that may require
custom or specialty cable assemblies. Americable, working to its customers'
specifications, can manufacture custom designed products such as copper,
fiber-optic, small computer system interface (SCSI) and AS/400 cable assemblies
and sub-assemblies.
 
     All Americable manufactured products are subject to strict quality control
standards to insure that they are of the same high quality as other, vendor
manufactured, distributed products. During 1996, Americable expects to complete
the process of implementing the quality standards of ISO 9002 for its
manufacturing and primary distribution operation in Minneapolis. ISO 9002 is an
international protocol for documenting processes and procedures used in
establishing a consistent manufacturing quality system.
 
                                       64
<PAGE>   73
 
     Sales from the Americable Custom Products division are generated from both
end-user and OEM customers. During 1996, Americable hopes to expand the market
for its custom and specialty cable assemblies, utilizing its in-house
manufacturing expertise of the Americable Custom Products division. For 1995,
sales to OEM customers constituted approximately 26% of total cable assembly
sales and approximately 5% of Americable's net sales.
 
     Transition. Transition's products encompass three inter-networking and
physical connectivity product families, which include (i) passive and active
terminal network products, (ii) basic LAN products and (iii) advanced LAN
products. These products encompass LAN and WAN components, which allow
Transition to offer work-group and enterprise-wide networking solutions.
 
     The terminal products family of products includes both passive and active
connectivity devices such as baluns, media converters, and transceivers that
attach personal computers to a network, thereby enabling the user to communicate
with other users in the LAN. In addition, Transition's "PowerStar" line of
active hubs provide cost-effective solutions for converting a S/3X or AS/400
Twinax daisy chain topology to an unshielded twisted pair star topology, thereby
improving network reliability and flexibility. During 1995, the terminal
products family comprised approximately 27% of Transition's net sales.
 
     Transition's basic LAN product line includes unmanaged Ethernet and Token
Ring hubs and related host modules; multi-port multi-media repeaters that
regenerate the signal, thereby allowing expansion capabilities and providing
connectivity and management of the different cabling schemes used throughout a
LAN; network adapter cards that provide direct connection from the personal
computer to a LAN; and other passive devices that provide a structured wiring
system for mini- and mainframe computer environments. Transition has developed
its Ethernet and Token Ring LAN products using industry standards. During 1995,
the basic LAN product line comprised approximately 63% of Transition's net
sales.
 
     The advanced LAN product family of Transition is a potentially high growth
product area with devices that utilize computer processors and sophisticated
internal software to manage and direct information across complex networks.
Transition's advanced LAN products are led by a multi-function hybrid
bridge/router that allows high speed switching across networks. This group of
products also includes manageable, stackable Ethernet and Token Ring hubs.
Transition believes that as network centric systems continue to grow in
sophistication, this product area will provide additional revenue opportunities.
The majority of Transition's research and development has been concentrated in
advanced LAN products with new offerings planned for 1996. During 1995, the
advanced LAN product family comprised approximately 10% of Transition's net
sales. Transition expects a significant portion of its sales growth in the
future will be derived from the introduction of new advanced LAN products.
 
MARKETING AND CUSTOMERS
 
     Americable. Americable provides its products and services to a wide range
of customers, including installers, resellers, other distributors, system
integrators, OEMs and end-users. Customer relationships are developed both
face-to-face and via the telephone.
 
     Americable's marketing strategy is two-tiered. A national effort is
centered on telemarketing through the National Distribution Sales division in
Minneapolis, Minnesota. Additionally, Americable operates each of its operating
divisions from its four principal regional offices in order to provide its
customers in each region the full array of value-added networking products and
services offered by the company.
 
     Americable has 16 outside sales representatives in addition to 43
telemarketing and sales support representatives. The sales force is supplemented
by 22 regional technical service engineers and technicians and two corporate
product managers. Americable sales representatives undergo continuous training
and attend company-sponsored classes in order to enhance their technical
expertise and marketing techniques. Also, many of Americable's sales and
technical personnel attend vendor-sponsored training and education programs
mandated by such vendors in order for Americable to qualify as a licensed
reseller of their products.
 
     Americable also uses direct mailings, brochures and catalogs in marketing
the products that it distributes. Americable's catalog, which generally is
published every 18 months, is designed to provide end-users with not
 
                                       65
<PAGE>   74
 
only product specifications, but additional technical information to assist them
in connection with their system design. Americable's latest catalog is expected
to be released in March 1996.
 
     During 1995, Americable had one customer that constituted approximately 11%
of net sales. In addition, in 1995 Americable derived approximately 61% of its
sales from its largest 100 customers.
 
     Transition. Transition distributes its products through a number of volume
distributors and VARs throughout the United States and in over 50 countries
worldwide. Distributors and VARs purchase Transition's products at standard
discounts based on certain volume-based incentive programs. Transition's
international sales have accounted for a substantial portion of its sales
growth, coming primarily from the United Kingdom, South Africa, Australia and
Sweden. During 1995, revenues from outside the United States accounted for
approximately 37% of net sales.
 
     Transition's continued growth will be dependent, in part, upon its ability
to expand its domestic and international distributor base with high quality
VARs. A significant benefit for a distributor or VAR is that Transition does not
sell directly to end users. Transition's distributors and VARs carry other
products that are complementary to, and compete with those of Transition, and
these non-exclusive distributors and VARs may choose to give higher priority to
products of other suppliers or competitors.
 
     Transition has several marketing programs to support the sale and
distribution of its products. Its marketing programs are designed to generate
sales leads for its distribution channels, as well as to enhance brandname
recognition. Transition's marketing activities include frequent participation in
industry trade shows, advertising in major trade publications, public relations
campaigns, the distribution of sales literature and product specifications, and
ongoing communications with its distributors. In addition, Transition offers
comprehensive pre- and post-sales technical support, distributor/VAR product
training, and a strategic test partner program. Transition utilizes reseller
incentive programs such as co-op funds to increase localized print advertising
and name recognition. The marketing budget has been increased for both 1995 and
1996 to enhance Transition's image and name recognition.
 
RESEARCH AND DEVELOPMENT
 
     Transition. Transition performs all of its research and development
activities at its headquarters in Eden Prairie, Minnesota. Transition believes
that its future success depends on its ability to achieve market acceptance of
new product offerings, especially in the advanced LAN products area. The
engineering staff has increased by 36% since the end of 1994, to accelerate
development in this area. Although there can be no assurance that its
development efforts will result in commercially successful products, Transition
intends to continue to make substantial investments in the development of new
and enhanced products. During 1995, research and development expenses totaled
approximately $1,440,000, or approximately 10% of net sales.
 
MANUFACTURING
 
     Americable. Americable's manufacturing operations consist of the
manufacture of custom or specialty cable assemblies including copper,
fiber-optic, small computer system interface (SCSI) and AS/400 cable assemblies
and sub-assemblies through its Americable Custom Products division.
 
     Transition. Transition's manufacturing operations consist primarily of the
final assembly and quality control testing of materials, components and
subassemblies. Transition uses third parties to perform printed circuit board
assembly. Transition's products include certain components that are currently
available from single or limited sources and may require long order lead times.
Any reduction in supply or substantial change in costs of components could
affect Transition's ability to deliver its products in a timely and
cost-effective manner and may adversely impact Transition's operating results.
 
COMPETITION
 
     Americable. Americable faces substantial competition within each of its
business segments from a large number of companies, some of which are larger,
have greater financial resources, broader name recognition and, in many cases,
lower product and operating costs than Americable. The Americable Network
 
                                       66
<PAGE>   75
 
Technologies division faces competition from large system integrators such as
AmeriData Technologies, Inc., Vanstar Corporation and a significant number of
smaller regional VAR's and system integrators. Significant competitors in the
National Distribution Sales division's business include Anixter Bros., Inc., a
subsidiary of Anixter International, Inc, and Graybar Electric Co., Inc. The
products of the Americable Custom Products division are not protected from
competition by virtue of any proprietary rights such as trade secrets or
patents. Americable Custom Products encounters competition from domestic
companies such as Kent Electronics Corporation and a number of smaller domestic
companies, in addition to a number of products manufactured outside the United
States.
 
     Transition. The industry in which Transition operates is highly
competitive, and Transition believes that such competition will continue to
intensify. The industry is characterized by rapid technological change, short
product life-cycles, frequent product introductions and evolving industry
standards. Transition competes with a number of independent companies focused on
designing and manufacturing products for the LAN market, including, among
others, 3Com, Bay Networks, Cabletron System, Inc., Allied Telesis, Inc., and
Digi International. Most of Transition's competitors are established companies
with significantly greater financial resources, more extensive business
experience, and greater market and service capabilities than Transition. There
can be no assurance that Transition will be able to compete successfully.
 
     Transition's ability to compete successfully depends upon its ability to
adapt to market changes on a timely basis. There are many networking products
currently being offered in the market segments in which Transition competes.
Transition believes that customers evaluate competing products on the basis of
required product features for a particular installation, performance, price and
ease of use. In addition, after installation, customers evaluate the suppliers'
ability to provide readily accessible on-site/remote technical support, if
required, and its reliability when deciding on future orders for additional
equipment. Failure to obtain significant customer satisfaction or market share
could have a material adverse effect on Transition.
 
PROPERTIES
 
     Americable. Americable's headquarters are located in a 20,000 square foot
facility in Itasca, Illinois, a suburb of Chicago. Americable's principal
distribution and manufacturing operations are located in Minneapolis, Minnesota
(39,000 square feet). This facility includes office, warehouse and production
space. Americable also has branch operations in Dallas, Texas (15,000 square
feet), and Atlanta, Georgia (9,900 square feet) in addition to satellite offices
in Milwaukee, Wisconsin and Fargo, North Dakota. All of Americable's facilities
are leased.
 
     Transition. Transition's headquarters, including its executive and
corporate administration offices, manufacturing, sales and technical support are
located in Eden Prairie, Minnesota, which consists of approximately 20,500
square feet of leased space.
 
LEGAL PROCEEDINGS
 
     Americable and Transition are engaged in routine litigation incidental to
their respective businesses, which management believes will not have a material
adverse effect upon the business or consolidated financial position of either
company.
 
NET ASSETS HELD FOR SALE
 
     NSU announced its intention to sell its wholly-owned subsidiary Eagle
Engineering & Manufacturing, Inc. ("Eagle") in March 1991. Eagle designs,
manufactures and installs a variety of environmental control systems for the
cabins of off-road heavy equipment, including air-conditioning, heating and
pressurization systems. Eagle is still wholly owned by NSU, although NSU is
hopeful that it will ultimately be able to sell this subsidiary on terms
acceptable to management. If Eagle is not sold prior to the consummation of the
Reorganization, Eagle will become a wholly owned subsidiary of ENStar and ENStar
management will also attempt to sell Eagle on acceptable terms.

         MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS
                       AND FINANCIAL CONDITION OF ENSTAR
 
GENERAL
 
     ENStar is currently an operating unit of NSU. ENStar is comprised of
Americable and Transition along with an equity investment in CorVel and certain
other assets. At December 31, 1995, NSU owned a 35% ownership interest in CorVel
and following the sale of 350,000 shares in January 1996, its ownership was
reduced to 27%. The financial statements of ENStar reflect the investment in
CorVel assuming ENStar owned a 27% ownership interest for all periods presented.
ENStar's investment in CorVel is accounted for as an unconsolidated subsidiary
using the equity method of accounting. The common stock of CorVel is included on
the NASDAQ National Market System under the symbol CRVL.
 
     As described in Note 2 to the Combined Financial Statements of ENStar, the
Combined Statements of Income of ENStar include an allocation of general and
administrative costs incurred by NSU in the management of the operating
companies, investment holding and other assets of ENStar. Management believes
these allocations are reasonable and present the operations of ENStar as though
it was operated on a stand alone basis.
 
     The following are summarized operating results for each of ENStar's
operations for the three years ended December 31, 1995 (in thousands):

RESULTS OF OPERATIONS
 
1995 VERSUS 1994
 
     Revenues at Americable increased approximately $5.2 million, or 14.1%, to
$42.1 million. This includes increased revenues of $4.5 million resulting from
higher demand for networking products. Of this amount,
 
                                       68
<PAGE>   77
 
approximately $3.1 million of sales were attributable to higher volume of
networking products with a large end user customer which is not expected to
continue during 1996. The increase in revenue of Americable also includes
approximately $650,000 of higher volume of service revenues due to increased
focus on services and the addition of technical personnel. In addition, sales of
cable assemblies increased by approximately $100,000 primarily a result of
higher demand of OEM assemblies offset by reduced pricing within modular
assembly applications due to technological changes.
 
     Revenues at Transition increased approximately $2.5 million, or 21% which
includes increased sales of approximately $1.1 million, or 25%, to international
customers and approximately $1.4 million, or 19% higher sales to domestic
customers. Sales to international customers consisted of 37% and 35% of
Transition's revenues in 1995 and 1994, respectively. This growth was due to
increased unit sales of its terminal products and both its basic and advanced
LAN product groups. Overall, these increases are primarily a result of new
product introductions during the end of 1994 and throughout 1995. During 1995,
new product introductions and enhancements accounted for $1.1 million, or 9% of
net sales. Transition's ability to maintain its present level of sales and its
continued sales growth is highly dependent upon its ability to offer new
products that meet customer's demands in a rapidly changing market, particularly
in light of the relatively short life cycle of its products.
 
     Combined gross profit, as a percentage of revenues, increased to 28% in
1995 as compared to 27.3% in 1994. Increased margins at Americable are primarily
attributable to a higher mix of value-added service revenue and, to a lesser
extent, improved pricing and improved manufacturing efficiencies within its
cable assembly operations. Decreased margins at Transition were a result of
lower pricing on certain product lines due to increased competition. For 1996,
ENStar expects its gross profit margins to decline due to expected competitive
pricing pressures on products sold by both Americable and Transition.
 
     ENStar's selling, general and administrative expenses increased $766,000,
or 5.6% to $14.3 million from $13.6 million in 1994. Operating expenses at
Americable increased approximately $600,000, or 7% which reflects higher selling
expenses of approximately $700,000 which is primarily a result of higher sales
commissions and the addition of technical and engineering personnel, along with
additional expense for amounts earned under its incentive compensation program
of approximately $200,000. These increases were offset by the impact of
approximately $300,000 of annualized savings realized through reorganizations
effected within its U.S. operations in the third quarter of 1994 and the first
quarter of 1995. Americable expects that its selling expenses, as a percentage
of revenues, may increase during 1996 through the addition of sales and
technical personnel in new geographic locations in addition to costs associated
with a new catalog expected for release in the first quarter of 1996. These
anticipated increases in operating expenses may result in lower operating
profits at Americable, if the company is unable to maintain current gross profit
margins and continued sales growth.
 
     Transition increased operating expenses approximately $213,000 or 5%. This
includes approximately $125,000 of increased sales and marketing expenses due to
higher promotional and advertising expenses associated with new product
introductions and the company's name change, and approximately $220,000 of
increased engineering expenses associated with the additional personnel to
support new product development. In addition, this increase reflects higher
expenses of approximately $175,000 related to moving to a new facility and the
addition of administrative personnel and related facility expenses needed to
support its overall growth. These increases were offset by a decrease in
engineering expenses of approximately $300,000 due to lower spending on parts,
equipment, and other costs related to hardware development projects. This
reflects a shift towards higher software development associated with its
advanced LAN products. Transition expects that its research and development
expenses will increase in 1996 based on the planned addition of engineering
personnel for new product development. There can be no assurances, however, that
its research and development efforts will result in commercially successful new
products in the future. In addition, Transition believes that sales and
marketing expenses may continue to increase in terms of absolute dollars in an
effort to differentiate its products and enhance its competitive position. These
anticipated increases in operating expenses are expected to result in lower
operating profit at Transition, particularly if the company is unable to
maintain its current gross profit margins and continued sales growth.

     Net interest expense decreased by approximately $100,000 due primarily to
lower outstanding borrowings under Americable's revolving credit facility.
 
     ENStar's effective combined income tax rate was 51.5% in 1995 and (32.4%)
in 1994. See Note 7 to the Combined Financial Statements of ENStar.
 
     Equity in earnings of unconsolidated subsidiary increased $195,000 to
approximately $1.2 million in 1995 from approximately $1 million in 1994, which
is a result of higher earnings at CorVel. CorVel's net earnings for the twelve
months ended December 31, 1995 were approximately $7 million, an increase of
approximately $1.5 million or 27% from the previous year.
 
1994 VERSUS 1993
 
     Revenues at Americable, excluding approximately $4.6 million of revenue in
1993 from its Canadian operations, which were closed in December 1993, increased
$3.3 million, or 9.8%, to $36.9 million. This includes increased revenues of $5
million resulting from higher demand for value-added networking products and
services offset by decreased sales of bulk cable and other connectivity products
of $1.2 million due primarily to lower volume of sales to contractors and
resellers. In addition, sales of cable assemblies decreased by approximately
$500,000 as a result of reduced pricing within modular assembly applications due
to technological changes.
 
     Revenues at Transition increased approximately $1.8 million, or 18% which
includes increased sales of approximately $1.1 million, or 33%, to international
customers and approximately $700,000, or 10% higher sales to domestic customers.
Sales to international customers consisted of 35% and 31% of Transition's
revenues in 1994 and 1993, respectively. Overall, these increases are primarily
a result of new product introductions during the end of 1993 and throughout
1994. During 1994, new product introductions and enhancements accounted for $3.3
million, or 28% of net sales.
 
     Combined gross profit, as a percentage of revenues, decreased to 27.3% in
1994 as compared to 30.3% in 1993. Margins at Americable decreased due to
overall lower pricing resulting from increased competition. Margins at
Transition were unchanged in 1994 from 1993.
 
     ENStar's selling, general and administrative expenses, excluding
restructuring charges, decreased $615,000, or 4.3% to $13.6 million from $14.2
million in 1993. Operating expenses at Americable decreased approximately $1.9
million, which reflects approximately $1.2 million of expenses eliminated
through the closure of its Canadian facilities effected in December 1993, and
$700,000 of other savings realized through a reorganization effected within its
U.S. operations in the third quarter. These decreases were offset by increased
expenses of $1.3 million at Transition due to the addition of sales and
engineering personnel and increased research and development expenses related to
new product introductions and additional administrative and support personnel
needed to support overall growth.
 
     Net interest expense was relatively unchanged between 1994 and 1993.
 
     ENStar's effective combined income tax benefit rate was 32.4% in 1994 and
3.0% in 1993. See Note 7 to the Combined Financial Statements.
 
     Equity in earnings of unconsolidated subsidiary increased $251,000 to
approximately $1 million in 1994 from $745,000 in 1993 which is a result of
higher earnings at CorVel. CorVel's net earnings for 1994 were approximately
$5.5 million, an increase of approximately $1.7 million or 43% from the previous
year.
 
CAPITAL RESOURCES AND LIQUIDITY
 
     ENStar had net cash from operations of approximately $1.5 million in 1995
versus net cash used in operations of approximately $1.1 million in 1994. The
increase in cash from operations is primarily a result of higher operating
profits at Americable and Transition. Historically, ENStar has experienced
fluctuations in its working capital which is primarily attributable to the
increase receivables and inventories associated with growth in sales and timing
of payments on accounts payable. For 1995 and 1994 cash provided by investing
activities primarily represents collections on notes receivable offset by
capital expenditures.
 
                                       70
<PAGE>   79
 
     Since CorVel's initial public offering in July 1991, ENStar has not had the
use of cash generated by CorVel and its subsidiaries. Also, since its initial
public offering, CorVel has not declared any dividends and has indicated that it
does not anticipate doing so for the foreseeable future. ENStar may from time to
time, depending on market conditions and other factors, sell a portion of its
CorVel holdings.
 
     Americable and Transition maintain a revolving line of credit and term loan
facility which provides borrowings up to $5.5 million due in May 1996.
Borrowings under the revolving credit facility are based on eligible accounts
receivable and inventory with interest at prime plus 1.5%, (10% at December 31,
1995). At December 31, 1995, there were outstanding borrowings of $937,000 under
the revolving credit facility and $1,071,000 under the term note. Management is
currently in the process of negotiating terms of a new credit facility and
expects to obtain available borrowing levels and terms that are comparable with
its existing facility.
 
     Upon completion of the Reorganization, ENStar intends to initiate a
program, similar to that historically maintained by NSU, whereby it will sell
subordinated debentures of various maturities to primarily individual investors.
The debentures are intended to be offered on a continuous basis at interest
rates that change from time to time depending on market conditions. Proceeds
from this program are intended to fund the growth of ENStar's operating
companies along with potential acquisitions and general corporate purposes.
There can be no assurance, however, that ENStar will implement this program or
that any attempted implementation of such a program would be successful.
 
     ENStar expects to be able to fund its working capital and capital
expenditure requirements for 1996 with cash flow from operations along with the
amounts available under the credit facilities of its operating companies. During
1996, ENStar's operating plans call for approximately $1 million in capital
expenditures.
 
                    COMPARISON OF RIGHTS OF NSU SHAREHOLDERS
                      BEFORE AND AFTER THE REORGANIZATION
 
     If the Reorganization is consummated, then after the Effective Time shares
of Common Stock of NSU will be exchanged for shares of Common Stock of New
Michael and ENStar. Like NSU and New Michael, ENStar is a Minnesota corporation
governed by Minnesota law, its Articles of Incorporation and its Bylaws.
Pursuant to the Reorganization, the existing Amended and Restated Bylaws of NSU
will become the Bylaws of New Michael. Such Amended and Restated Bylaws are
substantially the same as the Bylaws of ENStar. The existing Restated Articles
of Incorporation of NSU are referred to herein as the "NSU Articles." A copy of
the Amended and Restated Articles of Incorporation of NSU that will be adopted
if approved by the shareholders of NSU at the NSU Annual Meeting is included as
Exhibit D to Appendix I hereto. See "PROPOSAL NUMBER FOUR: PROPOSAL TO ADOPT AN
AMENDMENT TO THE RESTATED ARTICLES OF INCORPORATION OF NSU." Such Restated
Articles of Incorporation are referred to herein as the "New Articles." The
Restated Articles of Incorporation of ENStar are referred to herein as the
"ENStar Articles." There are certain differences between the NSU Articles, the
New Articles and the ENStar Articles. The following is a summary of some of the
significant differences.
 
     The NSU Articles provide for authorized Capital Stock of 100,035,000
shares, comprised of 100,000,000 shares of Common Stock with a par value of $.25
per share and 35,000 shares of preferred stock with a par value of $100 per
share. The New Articles will provide for authorized Capital Stock of 50,000,000
shares, comprised of 40,000,000 shares of common stock with a par value of $.01
per share and 10,000,000 undesignated shares. The New Articles will eliminate
the existing designation of the rights and preferences of NSU Common Stock and
NSU Preferred Stock. The Board of Directors will be able to establish by
resolution different classes or series of shares and to fix the rights and
preferences of any New Michael Preferred Stock to be issued. The rights and
preferences of New Michael Common Stock will be as provided under Minnesota law.
The ENStar Articles provide for authorized capital stock of 100,000,000,
comprised of 80,000,000 shares of Common Stock with a par value of $.01 per
share and 20,000,000 shares of Preferred Stock with a par value of $.01 per
share. All shares of ENStar Common Stock are voting shares and are entitled to
one vote per share. The board of directors has the authority to fix the rights
and preferences of preferred shares.
 
                                       71
<PAGE>   80
 
     The NSU Articles mandate that the Board of Directors consist of at least
one but not more than 15 directors. The New Articles will set the minimum number
of directors at three but will not fix a maximum number. It will also permit the
board, in its discretion, to elect honorary, non-voting directors. The ENStar
Articles fix the initial number of directors at five. Thereafter, the number of
directors may be fixed by the board or by the affirmative vote of voting power
of outstanding ENStar Common Stock.
 
     Under the NSU Articles, directors may take written action in lieu of action
at a meeting unless the matter requires shareholder approval. The number of
directors required to approve a written action is an absolute majority. Under
the New Articles, a written action on a matter requiring shareholder approval
must be signed by all directors. Written action on other matters may be taken by
an absolute majority of directors. The ENStar Articles are identical to the New
Articles in this respect.
 
     The NSU Articles do not explicitly require indemnification of directors,
officers or employees. The New Articles require NSU to indemnify any person who
was or is a party or is threatened to be made a party to any threatened, pending
or completed action, suit or proceeding, including an action by or in the right
of NSU to the fullest extent permitted under the Minnesota Business Corporation
Act. The ENStar Articles also require such indemnification.

</TABLE>
 
     See "ELECTION OF NSU DIRECTORS" for biographical information for Messrs.
Miles E. Efron, James H. Michael, Jeffrey J. Michael, Richard J. Braun and Peter
E. Flynn.
 
     Mr. Thomas Wargolet joined NSU in September 1989 and has been its
Controller since that time. Mr. Wargolet was also the Director of Finance of
Americable from September 1991 until January 1995. Since January 1995, Mr.
Wargolet has been the Vice President of Finance and Operations of Americable.
Prior to joining NSU in 1989, Mr. Wargolet was an Audit Senior with Arthur
Andersen & Co.
 
     Mr. Gary Eizenga joined Americable in September 1989 as Chief Operating
Officer and held that position until January 1991, at which time Mr. Eizenga
became President and Chief Executive Officer of Americable. Prior to joining
Americable, Mr. Eizenga held various positions with American Hospital Supply, a
division of Baxter International.
 
     Mr. Gary Doan founded Transition in 1987 and was its President until
December 1992, at which time he became Chairman and Chief Executive Officer.
 
     Officers of ENStar will be elected annually by the Board of Directors.
 
COMPENSATION OF EXECUTIVE OFFICERS OF ENSTAR
 
     ENStar will rely on the Compensation Committee of the Board of Directors
(composed of non-employee members) to recommend the form and amount of
compensation to be paid to ENStar executive officers.
 
                                       72
<PAGE>   81
 
     At the Compensation Committee meeting held on March 5, 1996, base annual
salaries for Messrs. Jeffrey J. Michael, Flynn and Wargolet of $175,000,
$150,000 and $90,000, respectively, were established by the Compensation
Committee and approved by the ENStar Board of Directors, subject to consummation
of the Reorganization. The Compensation Committee also discussed a proposed
bonus program that would provide for the payment of certain cash bonuses to the
ENStar officers based on ENStar's financial performance. Similar to the cash
bonus arrangements that NSU has established from time to time in the past, cash
bonuses for officers of ENStar would be earned based on a structured formula.
Performance targets would be established based on budgeted annual operating
results and cash bonuses would be calculated as a percentage of such officers'
base salary depending on actual financial performance compared to the
performance targets. It is anticipated that such bonuses will range from 0% to
75% of the officers' base salaries, depending upon the officer's position with
the Company. The establishment of the bonus program, the performance targets
relating thereto and the percentage of an officer's salary subject to such bonus
will be determined subsequent to the consummation of the Reorganization.
 
     Messrs. Doan and Eizenga will continue to receive the same base
compensation and participate in the incentive compensation programs at each of
Transition and Americable, respectively. Mr. Doan was paid a base salary of
$120,000 in 1995, and received a bonus of $24,000, based on Transition's 1995
financial performance. Mr. Eizenga was paid a base salary of $162,500 in 1995,
and received a bonus of $65,000, based on Americable's 1995 financial
performance.
 
     The Compensation Committee also approved the granting of non-qualified
stock options under the ENStar 1996 Stock Incentive Plan to each of Messrs.
Jeffrey J. Michael, Flynn and Wargolet at its March 5, 1996 meeting. Such
options provide for the purchase of 28,500, 23,500 and 14,250 shares of ENStar
Common Stock, respectively, at an exercise price per share of $9.00. The options
granted to Messrs. Jeffrey J. Michael, Flynn and Wargolet vest 25% per year over
four years and have a term of ten years. Such options terminate automatically if
the Reorganization is not consummated prior to the first anniversary of the date
of grant. The Compensation Committee currently does not plan to issue stock
options to Messrs. Doan and Eizenga.
 
     The Compensation Committee intends to generally adhere to compensation
policies that reflect the belief that ENStar must attract and retain individuals
of outstanding ability and motivate and reward such individuals for sustained
performance. The Committee also believes the ENStar levels of compensation
should generally be in line with what the executive officers of ENStar were
offered in their capacities as executive officers of NSU. On an ongoing basis,
the type and amount of compensation to be paid by ENStar to its officers will be
entirely discretionary and within the subjective judgment of the Compensation
Committee. It is currently anticipated that none of the officers of ENStar,
other than Messrs. Doan and Eizenga, will have employment agreements with
ENStar.
 
     For information concerning the compensation paid to the executive officers
of NSU for the 1995 fiscal year, see "ELECTION OF NSU DIRECTORS."
 
COMPENSATION OF DIRECTORS OF ENSTAR
 
     Directors who are not officers or employees of ENStar will receive an
annual retainer of $8,000. Such directors will also receive $300 per meeting for
each meeting of a committee of the Board of Directors that they attend.
Directors incurring travel expenses to attend meetings are reimbursed in full.
ENStar non-employee directors will also be eligible to receive certain stock
options pursuant to the ENStar 1996 Stock Incentive Plan discussed below.
 
COMMITTEES OF THE BOARD OF ENSTAR
 
     Audit Committee. ENStar has established a standing Audit Committee, which
consists of Mr. Efron and Mr. Braun with Mr. Braun serving as Chairman. The
Audit Committee will review and make recommendations and reports to the Board
with respect to (i) the independent auditors, (ii) the quality and effectiveness
of internal controls, (iii) engagement or discharge of the independent auditors,
(iv) professional services provided by the independent auditors, and (v) the
review and approval of major changes in NSU's accounting principals and
practices.

     Compensation Committee. ENStar has a standing Compensation Committee which
consists of Mr. Efron as Chairman and Mr. Braun. The Compensation Committee will
consider and recommend to the Board salary schedules and other remuneration for
ENStar's executive officers. This committee will also administer the ENStar 1996
Stock Incentive Plan.
 
1996 STOCK INCENTIVE PLAN
 
     On March 5, 1996, the Board of Directors of ENStar approved and adopted,
and NSU, as sole shareholder of ENStar, approved the ENStar 1996 Stock Incentive
Plan (the "Plan"). The following discussion of the Plan is qualified by
reference to the full text of the Plan which is available upon request to the
Secretary of ENStar.
 
     The purpose of the Plan is to promote the interests of ENStar and its
shareholders by aiding ENStar in attracting and retaining management personnel
capable of assuring the future success of, and non-employee directors capable of
providing strategic direction to ENStar, to offer such personnel and directors
incentives to put forth maximum efforts for the success of ENStar's business, to
afford such personnel and directors an opportunity to acquire a proprietary
interest in ENStar and to align further the interests of such personnel and
directors with ENStar's shareholders.
 
     Administration. With the exception of the provisions applicable to
non-employee directors, which are discussed below, the Plan will be administered
by the Compensation Committee of the Board of Directors of ENStar (the
"Committee"). The Committee has the authority to select the individuals to whom
awards are granted, to determine the types of awards to be granted and the
number of shares of ENStar Common Stock covered by such awards, to set the terms
and conditions of such awards, and to determine whether the payment of any
amounts received under any award shall or may be deferred. The Committee has the
authority to establish rules for the administration of the Plan, and
determinations and interpretations with respect to the Plan are at the sole
discretion of the Committee, whose determinations and interpretations are
binding on all interested parties. The Committee may delegate its powers and
duties under the Plan to one or more officers with respect to persons who are
not subject to Section 16 of the Exchange Act but it may not delegate any of its
powers and duties under the Plan in such a manner as would fail to comply with
any of the requirements of Section 162(m) of the Code.
 
     Terms of the Plan. The Plan permits the granting of a variety of different
types of awards: (i) stock options, including incentive stock options meeting
the requirements of Section 422 of the Code, and stock options that do not meet
such requirements (non-qualified stock options); (ii) stock appreciation rights
(SARs); (iii) restricted stock and restricted stock units; (iv) performance
awards; (v) dividend equivalents; and (vi) other awards valued in whole or in
part by reference to or otherwise based upon ENStar Common Stock ("other
stock-based awards"). Awards may be granted alone, in addition to, in tandem
with, or in substitution for any other award granted under the Plan or any other
plan. Awards may be granted for no cash consideration or for such minimal cash
consideration as may be required by applicable law. Awards may provide that upon
the grant or exercise thereof the holder will receive cash, shares of ENStar
Common Stock or other securities, awards or property, or any combination
thereof, as the Committee shall determine. The exercise price per share under
any stock option, the grant price of any SAR, and the purchase price of any
security which may be purchased under any other stock-based award under Section
6(f) of the Plan may not be less than 100 percent of the fair market value of
ENStar Common Stock on the date of the grant of such option, SAR or right.
Determinations of fair market value under the Plan are made in accordance with
methods and procedures established by the Committee.
 
     Options may be exercised by payment in full of the exercise price, either
in cash or, at the discretion of the Committee, in whole or in part by the
tendering of shares of ENStar Common Stock or other consideration having a fair
market value on the date the option is exercised equal to the exercise price.
The Plan provides that the Committee may grant "reload options," separately or
together with another option, and may establish the terms and conditions of such
reload options. Pursuant to a reload option, the optionee would be granted a new
option when the payment of the exercise price of the option to which such reload
option relates is made by using shares of ENStar Common Stock owned by the
optionee. The new option granted
 
                                       74
<PAGE>   83
 
upon such exercise would be an option to purchase the number of shares not
exceeding the sum of (i) the number of shares of ENStar Common Stock tendered as
payment upon the exercise of the option to which such reload option relates and
(ii) the number of shares of ENStar Common Stock tendered or withheld as payment
of the amount to be withheld under applicable tax laws in connection with the
exercise of the option to which such reload option relates. Reload options may
be granted with respect to options previously granted under the Plan or any
other stock option plan of ENStar, and may be granted in connection with any
option granted under the Plan or any other such plan at the time of such grant.
Such reload options shall have a per share exercise price equal to the fair
market value as of the date of grant of the new option. Any such reload option
shall be subject to availability of sufficient shares for grant under the Plan.
Shares surrendered as part or all of the exercise price of the option to which
it relates that have been owned by the optionee less than six months will not be
counted for purposes of determining the number of shares that may be purchased
pursuant to a reload option.
 
     The holder of an SAR is entitled to receive the excess of the fair market
value (calculated as of the exercise date or, if the Committee shall so
determine, as of anytime during a specified period before or after the exercise
date) of a specified number of shares over the grant price of the SAR.
 
     Shares of restricted stock and restricted stock units will be subject to
such restrictions as the Committee may impose (including any limitations on the
right to vote or the right to receive dividends), which restrictions may lapse
separately or in combination at such time or times, in such installments or
otherwise as the Committee may determine. Restricted stock may not be
transferred by the holder until the restrictions established by the Committee
lapse. Holders of restricted stock units have the right, subject to any
restrictions imposed by the Committee, to receive shares of ENStar Common Stock
at some future date. Upon termination of the holder's employment during the
restriction period, restricted stock and restricted stock units are forfeited,
unless the Committee determines otherwise.
 
     Performance awards provide the holder thereof the right to receive
payments, in whole or in part, upon the achievement of such goals during such
performance periods as the Committee shall establish. A performance award
granted under the Plan may be denominated or payable in cash, shares of ENStar
Common Stock or restricted stock or restricted stock units, or other securities,
awards or property. Dividend equivalents entitle the holder thereof to receive
payments (in cash, shares or otherwise, as determined by the Committee)
equivalent to the amount of cash dividends with respect to a specified number of
shares. The Committee is also authorized to establish the terms and conditions
of other stock-based awards.
 
     Restrictions on Awards and Transfers. No person who is an employee of
ENStar at the time of grant may be granted any award or awards under the Plan,
the value of which awards are based solely on an increase in the value of the
shares after the date of grant of such awards, of more than 170,000 shares, in
the aggregate, in any calendar year. The foregoing annual limitation
specifically includes the grant of any awards representing "qualified
performance-based compensation" within the meaning of Section 162(m) of the
Code.
 
     No award granted under the Plan may be assigned, transferred, pledged or
otherwise encumbered by the individual to whom it is granted, otherwise than by
will or the laws of descent and distribution, except that the Committee may
permit the designation of a beneficiary. Each award is exercisable, during such
individual's lifetime, only by such individual or, if permissible under
applicable law, by such individual's guardian or legal representative.
 
     The aggregate number of shares of ENStar Common Stock that may be issued
under all awards granted under the Plan is 300,000 (subject to adjustment as
described below). If any shares of ENStar Common Stock subject to any award or
to which an award relates are not purchased or are forfeited, or if any such
award terminates without the delivery of shares, the shares previously set aside
for such awards will be available for future awards under the Plan.
Notwithstanding the foregoing, the total number of shares of ENStar Common Stock
that may be purchased upon exercise of incentive stock options granted under the
Plan may not exceed 300,000, subject to adjustment as described below and in
Section 422 or 424 of the Code or any successor provision. Shares relating to
awards that allow the holder to receive or purchase shares will be counted
against the aggregate number of shares available for granting awards under the
Plan.
 
                                       75
<PAGE>   84
 
     If any dividend or other distribution, recapitalization, stock split,
reverse stock split, reorganization, merger, consolidation, split-up, spin-off,
combination, repurchase, or exchange of shares of ENStar Common Stock or other
securities of ENStar, issuance of warrants or other rights to purchase shares of
ENStar Common Stock or other securities of ENStar, or other similar corporate
transaction or event affects the shares of ENStar Common Stock so that an
adjustment is appropriate in order to prevent dilution or enlargement of the
benefits or potential benefits intended to be made available under the Plan, the
Committee shall, in such manner as it deems equitable, adjust any or all of (i)
the number and type of shares (or other securities or property) which thereafter
may be made the subject of awards, (ii) the number and type of shares (or other
securities or property) subject to outstanding awards and (iii) the exercise
price with respect to any award.
 
     Termination. The Plan terminates on March 5, 2006, and no awards may be
made after that date. Unless otherwise expressly provided in the Plan or an
applicable award agreement, however, any award granted may extend beyond the end
of such period.
 
     Amendment. The Board of Directors may amend, alter or discontinue the Plan
at any time, provided that shareholder approval must be obtained for any such
action that, absent such shareholder approval, would (i) cause Rule 16b-3 under
the Exchange Act to become unavailable with respect to the Plan; (ii) violate
the rules or regulations of the Nasdaq National Market any other securities
exchange applicable to ENStar; or (iii) cause ENStar to be unable, under the
Code, to grant incentive stock options under the Plan. The Committee may correct
any defect, supply any omission, or reconcile any inconsistency in the Plan or
any award agreement in the manner and to the extent it shall deem desirable to
carry the Plan into effect. The Committee may waive any condition of, or rights
of ENStar under any outstanding award, prospectively or retroactively, but the
Committee may not amend or terminate any outstanding award, prospectively or
retroactively, without the consent of the holder or beneficiary of the award.
 
     Federal Tax Consequences. The following is a summary of the principal
federal income tax consequences generally applicable to awards under the Plan.
 
     The grant of an option or SAR is not expected to result in any taxable
income to the recipient. The holder of an incentive stock option generally will
have no taxable income upon exercising the incentive stock option (except that a
liability may arise pursuant to the alternative minimum tax), and ENStar will
not be entitled to a tax deduction when an incentive stock option is exercised.
Upon exercising a non-qualified stock option, the optionee must recognize
ordinary income equal to the excess of the fair market value of the shares of
ENStar Common Stock acquired on the date of exercise over the exercise price,
and ENStar will be entitled at that time to a tax deduction in the same amount.
Upon exercising an SAR, the amount of any cash received and the fair market
value on the exercise date of any shares of ENStar Common Stock received are
taxable to the recipient as ordinary income and deductible by ENStar. The tax
consequence to an optionee upon a disposition of shares acquired through the
exercise of an option or SAR will depend on how long the shares have been held
and upon whether such shares were acquired by exercising an incentive stock
option or by exercising a non-qualified stock option or SAR. Generally, there
will be no tax consequence to ENStar in connection with disposition of shares
acquired under an option, except that ENStar may be entitled to a tax deduction
in the case of a disposition of shares acquired under an incentive stock option
before the applicable incentive stock option holding periods set forth in the
Code have been satisfied.
 
     With respect to other awards granted under the Plan that are payable either
in cash or shares of ENStar Common Stock that are either transferable or not
subject to substantial risk of forfeiture, the holder of such an award must
recognize ordinary income equal to the excess of (i) the cash or the fair market
value of the shares of ENStar Common Stock received (determined as of the date
of such receipt) over (ii) the amount (if any) paid for such shares of ENStar
Common Stock by the holder of the award, and ENStar will be entitled at that
time to a deduction for the same amount. With respect to an award that is
payable in shares of ENStar Common Stock that are restricted as to
transferability and subject to substantial risk of forfeiture, unless a special
election is made pursuant to the Code, the holder of the award must recognize
ordinary income equal to the excess of (i) the fair market value of the shares
of ENStar Common Stock received (determined as of the first time the shares
become transferable or not subject to substantial risk of forfeiture,
 
                                       76
<PAGE>   85
 
whichever occurs earlier) over (ii) the amount (if any) paid for such shares of
ENStar Common Stock by the holder, and ENStar will be entitled at that time to a
tax deduction in the same amount.
 
     Special rules may apply in the case of individuals subject to Section 16 of
the Exchange Act. In particular, unless a special election is made pursuant to
the Code, shares received pursuant to the exercise of a stock option or SAR may
be treated as restricted as to transferability and subject to a substantial risk
of forfeiture for a period up to six months after the date of exercise.
Accordingly, the amount of any ordinary income recognized, and the amount of
ENStar's tax deduction, are determined as of the end of such period.
 
     Under the Plan, the Committee may permit participants (other than
non-employee directors) receiving or exercising awards, subject to the
discretion of the Committee and upon such terms and conditions as it may impose,
to surrender shares of ENStar Common Stock (either shares received upon the
receipt or exercise of the award or shares previously owned by the optionee) or
other property to ENStar to satisfy federal and state tax obligations. In
addition, the Committee may grant, subject to its discretion and such rules as
it may adopt, a bonus to a participant (other than a person subject to Section
16 of the Exchange Act) in order to provide funds to pay all or a portion of
federal and state taxes due as a result of the receipt or exercise of (or lapse
of restrictions relating to) an award. The amount of any such bonus will be
taxable to the participant as ordinary income, and ENStar will have a
corresponding deduction equal to such amount (subject to the usual rules
concerning reasonable compensation).
 
     Eligible Employees. Any employee, officer, consultant or independent
contractor of ENStar and its affiliates selected by the Committee is eligible to
receive an award under the Plan. Other than as described elsewhere herein, the
amount, type and recipients of awards under the Plan have not yet been
determined.
 
     Non-employee Directors. Each non-employee director of ENStar, upon his or
her initial election as a director, shall be granted an option to purchase 4,000
shares of ENStar Common Stock. Commencing with the 1997 Annual Meeting, each
non-employee director of ENStar also shall be granted an option to purchase
1,000 shares of ENStar Common Stock on the date of the annual meeting of
shareholders each year if the director will remain in office immediately
following such meeting. The exercise price of each option shall be equal to 100
percent of the fair market value per share on the date of grant. Such options
shall be non-qualified stock options, shall become exercisable six months after
the date of grant, and shall terminate on the fifth anniversary of the date of
grant. Such options shall also terminate three months following the date upon
which the participant ceases to be a director of ENStar, except that if the
participant shall cease to be a director by reason of willful and material
misconduct, the option shall terminate as of the date of such misconduct, and if
the participant shall die while a director of ENStar and he or she shall not
have fully exercised the option, the option may be exercised at any time within
twelve months after the participant's death, in accordance with its terms by the
participant's legal representatives, but only to the extent of the full number
of shares the participant was entitled to purchase under the option on the date
of death.
 
     In connection with their election as directors and the adoption of the
Plan, each of Messrs. James H. Michael, Miles E. Efron and Richard J. Braun were
granted an option to purchase 4,000 shares of ENStar Common Stock. The exercise
price of such options is at $9.00 per share. The options are expressly subject
to the consummation of the Reorganization.
 
EIZENGA AGREEMENT
 
     Gary L. Eizenga is a party to a Stock Option Agreement, dated September 27,
1989, pursuant to which he was granted an option to purchase from NSU up to 500
shares of the common stock of Americable, or approximately 2.5% of the
outstanding shares of Americable, subject to adjustment in the event of a
recapitalization, stock-split or stock dividend, at a price per share equal to
the book value per share as of September 30, 1989, which was $873.12. Such
option is exercisable through October 1, 1999, except that in the event of
termination of Mr. Eizenga's employment, the option may be exercised only for a
period of 90 days after such termination. The option may terminate as of an
earlier date in the event of dissolution or liquidation of Americable. Mr.
Eizenga and NSU are currently discussing a possible restructuring of Mr.
Eizenga's option in connection with the Reorganization.

DOAN AGREEMENT
 
     Gary M. Doan is a party to an employment agreement with Transition, the
original term of which expired December 31, 1994, but which has been
automatically extended by the parties for successive one-year periods since that
date. As extended, the agreement provides for an annual base salary of $120,000
in connection with Mr. Doan's services rendered for the benefit of Transition.
The agreement entitles Mr. Doan to participate in executive compensation
programs established by Transition's Board of Directors. Mr. Doan is also
eligible to receive an annual cash bonus to be determined based on Transition's
financial performance. Mr. Doan received a bonus of $24,000 based on
Transition's performance during 1995.
 
     The agreement may be terminated by either party at the end of an extension
period upon at least 60 days written notice. If Transition terminates Mr. Doan's
employment without sufficient notice or without cause, Mr. Doan is entitled to
be paid the base salary then in effect for a period of six months.
 
     In connection with Gary M. Doan's employment with Transition as of May 1,
1992, Mr. Doan was granted an option to purchase up to 4.5% of the Common Stock
of Transition at a price equal to the fair market value on May 1, 1992.
Approximately two thirds of the award was exercisable by May 1994. The remainder
is exercisable December 31, 2001. The option expires April 30, 2002, except that
in the event Mr. Doan's employment is earlier terminated for whatever reason,
the portion of the award that is exercisable or which will become exercisable
within 90 days may be exercised until the earlier of 90 days after such
termination or May 31, 2002. Any shares purchased by Mr. Doan are subject to
repurchase by NSU if Mr. Doan ceases to be employed by Transition.
 
                             PROPOSAL NUMBER FOUR:
                     PROPOSAL TO ADOPT AN AMENDMENT TO THE
                   RESTATED ARTICLES OF INCORPORATION OF NSU
 
     On March 5, 1996, the Board of Directors of NSU unanimously adopted a
resolution approving amendments to and a restatement of NSU's existing Restated
Articles of Incorporation, subject to the consummation of the Reorganization.
The Board further resolved that the amendments be submitted to shareholders of
NSU for their approval, subject to the consummation of the Reorganization. A
copy of the Amended and Restated Articles of Incorporation is included in
Appendix I as Exhibit D to the Reorganization Agreement. Such Amended and
Restated Articles of Incorporation are referred to herein as the "New Articles."
If approved by the shareholders of NSU, the New Articles would be filed with the
Minnesota Secretary of State on the Effective Date.
 
     Michael has requested the changes to the Restated Articles of Incorporation
of NSU as described below, as a condition to the Merger, in order to ensure that
the Articles of New Michael will better conform to the existing Certificate of
Incorporation of Michael. The Board of Directors of NSU believes that the
amendments are appropriate in light of the Reorganization.
 
     Under the New Articles, NSU's name will be changed to Michael Foods, Inc.
 
     Article IV of the existing Restated Articles of Incorporation of NSU would
be amended by decreasing the number of shares of authorized Capital Stock of NSU
from 100,035,000 shares, comprised of 100,000,000 shares of Common Stock with a
par value of $.25 per share and 35,000 shares of preferred stock with a par
value of $100 per share, to 50,000,000 shares comprised of 40,000,000 shares of
common stock with a par value of $.01 per share and 10,000,000 undesignated
shares. Each share of New Michael Common Stock will be entitled to one vote on
all matters presented to the shareholders for a vote. Article IV of the New
Articles would eliminate the current designation of the rights and preferences
of NSU Common Stock and NSU Preferred Stock. The Board of Directors will be able
to establish by resolution different classes or series of shares and to fix the
rights and preferences of any New Michael Preferred Stock to be issued. The
rights and preferences of New Michael Common Stock will be as provided under
Minnesota law.
 
     The current Restated Articles of Incorporation of NSU mandate that the
Board of Directors consist of at least one but not more than 15 directors.
Article VI of the New Articles will set the minimum number of
 
                                       78
<PAGE>   87
 
directors at three but will not fix a maximum number. It will also permit the
board, in its discretion, to elect honorary, non-voting directors. In addition,
Article VI of the New Articles will explicitly state that the Board of Directors
has all the powers conferred upon directors under the Minnesota Business
Corporation Act.
 
     Under the existing Restated Articles of Incorporation of NSU, an absolute
majority of directors may take written action in lieu of action at a meeting,
except when the matter to be acted on requires shareholder approval. When an
action taken by the board must be approved by shareholders, however, a written
action must be approved by an absolute majority of directors. Under the New
Articles, a written action on a matter requiring shareholder approval must be
signed by all directors. Other matters may be acted upon by written action
signed by an absolute majority of the directors.
 
     The New Articles will also require New Michael to indemnify any person who
was or is a party or is threatened to be made a party to any threatened, pending
or completed action, suit or proceeding, including an action by or in the right
of NSU to the fullest extent permitted under the Minnesota Business Corporation
Act. The existing Restated Articles of Incorporation of NSU do not explicitly
require such indemnification.
 
     If approved, the amendments to and restatement of the Restated Articles of
Incorporation of NSU will, subject to the consummation of the Reorganization,
become effective upon filing with the Minnesota Secretary of State, which would
take place on the Effective Date. The Board of Directors recommends a vote FOR
approval of the New Articles. Under Minnesota law the affirmative vote of a
majority of the outstanding shares of NSU Common Stock is necessary to approve
the New Articles.
 
                             PROPOSAL NUMBER FIVE:
                           ELECTION OF NSU DIRECTORS
 
     The Board of Directors of NSU has recommended that the number of Directors
to be elected for the coming year be set at six. The Board of Directors
recommends that shareholders elect the nominees named below as Directors of NSU
for the ensuing year and until their successors are elected and qualified.
Unless otherwise indicated thereon, the persons named in the enclosed form of
proxy intend to vote FOR the election of the six nominees listed below. The
affirmative vote of a majority of the shares of NSU Common Stock present (or
represented by proxy) and entitled to vote at the 1996 Annual Meeting is
required to elect each of the nominees as Directors for the ensuing year or
until their successors are elected and have qualified. All of the nominees are
members of the present Board of Directors. If for any reason any nominee shall
be unavailable for election to the Board of Directors, votes will be cast
pursuant to authority granted by the enclosed proxy for such other candidate or
candidates as may be nominated by the Board of Directors. The Board of Directors
has no reason to believe that any of the nominees listed below will be unable to
serve if elected to office. If the Reorganization is consummated, NSU and
Michael currently contemplate that the members of the Board of Directors of NSU
other than Mr. Efron and Mr. Michael will resign as of the Effective Date and
Mr. Efron and Mr. Michael will name certain Michael-designated individuals to
the Board of Directors of New Michael. See "THE REORGANIZATION AGREEMENT -- New
Michael Management Following the Reorganization."

DIRECTOR COMPENSATION
 
     During 1995, Directors of NSU, other than Messrs. Jeffrey J. Michael and
Flynn, who are also executive officers of NSU, received a monthly retainer of
$600 for serving as members of NSU's Board of Directors. Directors incurring
travel expenses to attend meetings are reimbursed in full. Members of the Audit
Committee, other than Mr. Flynn, each receive an additional $300 for each
committee meeting held. The total of all such payments for the year ended
December 31, 1995 was $30,000.
 
REPORT OF THE EXECUTIVE COMMITTEE OF THE BOARD OF DIRECTORS ON EXECUTIVE
COMPENSATION
 
     General. The Executive Committee of the Board of Directors (the
"Committee") establishes the specific compensation for each of NSU's named
executive officers. The Committee is made up of three members, James H. Michael,
Miles E. Efron and Jeffrey J. Michael. With respect to compensation matters
concerning Mr. Jeffrey J. Michael, NSU's President and Chief Executive Officer,
Mr. Jeffrey J. Michael is excluded from Committee deliberations. After
consideration of the Committee recommendations, the full Board of Directors
reviews and approves the salaries of each named executive officer. The Committee
is responsible for administering all other elements of executive compensation,
including annual incentive awards and stock option grants.
 
     Executive Compensation Philosophy and Goals. During 1991 NSU initiated a
strategic process to strengthen its balance sheet and focus its management
resources on its key holdings. In connection with this process NSU sold several
of its smaller businesses and substantially cut corporate overhead. As a result,
NSU has only two executive officers, Jeffrey J. Michael, President and Chief
Executive Officer, and Peter E. Flynn, Executive Vice President, Chief Financial
Officer and Secretary. The Committee believes that NSU's success depends to a
significant extent on the continuing efforts and dedication of Messrs. Jeffrey
J. Michael and Flynn. The executive compensation arrangements are designed to
motivate and reward these executives for attaining the financial and strategic
objectives essential to NSU's success and continued growth, while at the same
time allowing NSU to retain high-caliber executives. The key components of NSU's
compensation program are base salary, cash bonuses and, to a lesser extent,
stock option awards.
 
     Base Salaries. While the Committee has not conducted formal independent
salary comparisons in determining individual executive compensation, the
Committee believes that base salaries should be moderate, yet competitive in
relation to salaries commanded by persons in similar positions. The base salary
for each named executive officer is reviewed annually and is set on the basis of
personal performance, the relative importance of the functions the officer
performs, the scope of the officer's ongoing responsibilities and the estimated
salary levels in effect at comparable companies for comparable positions. The
weight given to each of these factors varies between individuals.
 
     Cash Bonuses. Annual cash bonuses are designed to reward executives with
operating responsibility for personal contributions to the success of NSU and
generally are earned under a structured formula. Historically, individual
performance targets have been established based on an annual operating budget
which is submitted for review and approval by the Chief Executive Officer of NSU
after consultation with the Committee. After the end of the calendar year, the
Chief Executive Officer has evaluated actual financial performance against the
individual performance targets. In the case of Mr. Flynn, who had day-to-day
responsibility for the operation of Transition during 1995 (in addition to his
responsibilities as an executive officer of NSU), the Committee departed from
this practice in 1995 because of the change in Mr. Flynn's responsibilities on
April 1, 1995, which are described below in this report. In 1993, the Committee
discontinued payment of discretionary bonuses for officers without direct
operating responsibility. Accordingly, Mr. Michael has not received a cash bonus
since 1992.
 
     Stock Options. Incentive stock options are periodically granted to motivate
executives to achieve positive long-term financial results, thereby enhancing
shareholder value. Due to the limited corporate staff, NSU does not have formal
policies or formulas for determining the timing, amount or particular vesting
schedules for stock option awards. Furthermore, NSU's stock performance is
significantly affected by changes in the value of its equity holdings in Michael
and, to a lesser extent, the value of its CorVel holdings. Although North Star
has representatives on the boards of directors of both Michael and CorVel, NSU
does not have direct
 
                                       82
<PAGE>   91
 
management control over the operations of either business. Accordingly, the
Committee believes that NSU's stock performance is often not the best indicator
of the performance of NSU's management team, and, as a result, has not granted
significant options to NSU's executives. Further, because of the substantial
beneficial holdings of Mr. Michael's family in NSU's Common Stock, the Committee
believes Mr. Michael's interests in stock performance already parallel those of
NSU's other shareholders. As a result, the Committee historically has not
granted any stock options to Mr. Michael. During 1995, there were no stock
options granted to any executive officer.
 
     1995 Executive Compensation. Mr. Jeffrey J. Michael, as Chief Executive
Officer of North Star, has overall responsibility for the strategic direction of
NSU and for the performance of NSU's wholly owned operating companies. Mr.
Michael was elected to his present position in December 1990 and is not a party
to an employment agreement. During 1994 and 1995, Mr. Michael was paid a base
salary of $235,000. In establishing Mr. Michael's base salary, the Committee
took into account that Mr. Michael does not participate in NSU's incentive cash
bonus program or employee stock option plan. Mr. Michael's base salary was
continued at $235,000 in 1996.
 
     As described in more detail below, Mr. Flynn entered into an employment
agreement with NSU and Transition effective April 1, 1993, in connection with
his assumption of the duties of President of Transition, which agreement was
modified effective as of April 1, 1995. The modification to his agreement with
NSU and Transition provided that Mr. Flynn devote more of his time to NSU
matters while continuing to oversee the day-to-day operations of Transition.
During 1995, approximately 24% of Mr. Flynn's base salary was paid by Transition
and related to his work as President of that company. The remainder of his base
salary in 1995 was paid by NSU recognizing his greater involvement in NSU
matters. In 1995, Mr. Flynn's base salary remained relatively unchanged from his
base salary in 1994. Also, for 1995, Mr. Flynn was awarded a bonus of $25,000
based on the performance of Transition through the first quarter of 1995, and a
discretionary bonus of $75,000, based on his performance in executing NSU's
strategic plans.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     Jeffrey J. Michael, James H. Michael and Miles E. Efron served on the
Executive Committee of NSU for the past fiscal year. The Executive Committee
determines compensation levels for NSU's executive officers. Each of Messrs.
James H. Michael and Efron was formerly an executive officer of NSU, and James
H. Michael has on occasion borrowed funds from NSU. As of February 21, 1996, Mr.
Michael owed NSU approximately $157,872. The maximum amount of such
indebtedness, including accrued but unpaid interest, owed to NSU by Mr. Michael
during 1995 was approximately $428,084. The currently outstanding indebtedness
is evidenced by an unsecured note which provides for quarterly interest payments
and an annual principal payment of $50,000. The unsecured note accrues interest
at the rate of one percent over the reference rate of First Bank, National
Association (9.25% at February 21, 1996).
 
     Effective September 1, 1985, the Board of Directors established a formal
policy governing future loans to officers. The policy permits unsecured loans to
officers of up to $50,000. Loans in excess of $50,000 must be approved in
advance by the Board of Directors and must be secured by readily marketable
negotiable securities. Loans to officers will bear interest at one percent over
the prevailing prime rate of interest and must mature within five years.
Interest is to be paid quarterly. In addition to the foregoing, an officer may
borrow annually an amount not exceeding 10 percent of annual compensation. These
loans are without interest and are payable on termination of employment. Mr.
James H. Michael's loans from NSU predate this policy.

     Although Jeffrey J. Michael, NSU's President and Chief Executive Officer,
served on NSU's Executive Committee during 1993 and 1994, as previously
indicated, he did not participate in any decisions regarding his own
compensation as an executive officer.

EMPLOYMENT CONTRACTS AND TERMINATION OF EMPLOYMENT ARRANGEMENTS
 
     Effective December 31, 1990, Mr. Efron's employment agreement with NSU was
terminated, and he resigned as President and Chief Executive Officer of NSU. Mr.
Efron continues as an employee of NSU, providing advisory and consulting
services. Pursuant to an agreement with NSU, he continues to receive annual
compensation of $50,000 through December 1996 for his consulting and advisory
services to NSU and is eligible to participate in other fringe benefits
established by NSU for its executive officers.
 
     Mr. Flynn is a party to an employment agreement with NSU and Transition,
which terminates December 31, 1997, subject to annual extensions thereafter at
the option of the parties. Mr. Flynn's employment agreement was modified
effective April 1, 1995. As modified, the agreement provides for an annual base
salary of $136,000 for services rendered for the benefit of NSU, plus annual
compensation of $42,500 in connection with Mr. Flynn's duties as President and
Chief Operating Officer of Transition. The agreement entitles Mr. Flynn to
participate in other fringe benefits established by NSU for its executive
officers. In addition, Mr. Flynn was awarded a bonus of $25,000 based on the
performance of Transition through the first quarter of 1995, and Mr. Flynn was
made eligible for a discretionary bonus in 1996 based upon his performance in
1995 in executing NSU's strategic plans. Under the terms of the agreement, the
amount of the discretionary bonus was limited to $75,000, as determined by NSU's
Board of Directors. The Board subsequently determined that Mr. Flynn should be
awarded the maximum amount of the discretionary bonus.
 
     Upon the voluntary termination of his employment with NSU, Mr. Flynn is
entitled to receive a single lump sum payment equal to his then current base
salary plus $25,000. If Mr. Flynn dies, he becomes disabled and unable to
continue his employment, his employment is terminated by NSU for any reason, or
he voluntarily terminates his employment following certain actions by NSU
constituting constructive termination, Mr. Flynn is entitled to receive a single
lump sum payment equal to two times his then current base salary plus $25,000.
If Mr. Flynn's employment is terminated due to a change in control of NSU, Mr.
Flynn is entitled to receive a single lump sum payment of $297,000. Also, if Mr.
Flynn is terminated by NSU, all of his then outstanding options immediately
become vested.

COMPLIANCE WITH SECTION 16(A) OF THE EXCHANGE ACT
 
     Section 16(a) of the Securities Exchange Act of 1934 requires executive
officers and directors and persons who beneficially own more than ten percent
(10%) of NSU's Common Stock to file initial reports of ownership and reports of
changes in ownership with the Commission. Executive officers, directors, and
greater than ten percent (10%) beneficial owners are required by Commission
regulations to furnish NSU with copies of all Section 16(a) forms they file.
 
     Based solely on a review of the copies of such forms furnished to NSU and
written representations from the executive officers and directors of NSU, NSU
believes that its executive officers, directors and 10% shareholders complied
with all Section 16(a) filing requirements applicable to them, except that
Messrs. James H. Michael and Jeffrey J. Michael each reported one transaction
late for the year ending December 31, 1995.

                     NOTES TO COMBINED FINANCIAL STATEMENTS
 
NOTE 1 -- ORGANIZATION AND BUSINESS
 
     ENStar (the "Operating Unit" or the "Unit") is an Operating Unit of North
Star Universal, Inc. ("North Star"). The Operating Unit is comprised of
Americable, Inc. ("Americable"), Transition Networks, Inc., ("Transition") and
Eagle Engineering and Manufacturing, Inc. ("Eagle," which is included in net
assets held for sale), along with an equity investment in CorVel Corporation
("CorVel") and certain other assets. At December 31, 1995, North Star owned a
35% ownership interest in CorVel and following the sale of 350,000 shares in
January 1996, its ownership was reduced to 27%. The accompanying financial
statements reflect a 27% ownership interest for all periods presented. The
Operating Unit's investment in CorVel is accounted for as an unconsolidated
subsidiary using the equity method of accounting.
 
     Americable is a provider of connectivity and networking products and
services. Transition designs, manufactures and markets connectivity devices used
in network applications.
 
     Pursuant to the terms of an agreement between North Star and Michael Foods,
Inc. ("Michael Foods"), an unconsolidated subsidiary of North Star will be
merged with and into Michael Foods and the net assets owned by the Unit will be
transferred to a newly formed corporation ENStar Inc. Under the terms of the
agreement, the shares of ENStar Inc. will be declared payable in a tax free
dividend to the North Star shareholders of record prior to the effective date of
such merger and distributed immediately following the merger. The transaction is
subject to the receipt of a favorable ruling from the Internal Revenue Service
that the transactions are tax free to the shareholders of Michael Foods and
North Star, the approval of both companies shareholders and other closing
conditions.
 
NOTE 2 -- SUMMARY OF ACCOUNTING POLICIES
 
     BASIS OF PRESENTATION The accompanying combined financial statements have
been prepared from the books and records of the entities and investments
described in Note 1. The combined financial statements include an allocation of
general and administrative costs incurred by North Star in the management of the
operating companies, investment holding and other assets of the Unit. Management
believes these allocations are reasonable and present the operations of the Unit
as though it was operated on a stand alone basis. Additionally, operating unit
equity includes the historical equity of each entity, other net assets
contributed to the Unit and intercompany payables owed to North Star. The annual
net advances between the Unit and North Star are considered additional capital
invested from, or constructive dividends to, North Star. Accordingly, the
accompanying combined financial statements may not necessarily be indicative of
the results that would have been obtained if the Unit had been operated as a
stand alone entity.
 
     PRINCIPLES OF COMBINATION Significant inter-unit balances and transactions
have been eliminated.
 
     CASH AND CASH EQUIVALENTS The Unit considers its highly liquid temporary
investments with original maturities of three months or less to be cash
equivalents. The carrying value of cash and cash equivalents approximate fair
value because of the short-term maturity of these investments.
 
     INVENTORIES Inventories are stated at the lower of average cost (determined
on a first-in, first-out basis) or market. At December 31, inventories consist
of the following (in thousands):

     GOODWILL Goodwill is amortized on a straight-line basis over periods not
exceeding 40 years. Accumulated amortization was $1,584,000 at December 31, 1995
and $1,423,000 at December 31, 1994. The Unit maintains separate financial
records for each of its acquired entities and evaluates its goodwill annually to
determine potential impairment by comparing the carrying value to the
undiscounted future cash flows of the related assets. The Unit modifies the life
or adjusts the value of a subsidiary's goodwill if an impairment is identified.
See Note 3 for an impairment identified during 1993.
 
     REVENUE RECOGNITION The Unit recognizes revenue from product sales at the
time product is shipped to a customer. Service revenue is recognized at the time
service is provided or ratably over the contractual service period.
 
     PRO FORMA INCOME (LOSS) PER SHARE Pro forma income (loss) per share was
computed based on the weighted average number of shares of North Star common
stock outstanding (9,650,000, 9,704,000 and 9,438,000 in 1995, 1994 and 1993)
after giving effect to the assumed exercise of North Star's outstanding stock
options for North Star common stock, except when the effects are antidilutive.
This weighted average number of shares was adjusted to reflect the distribution
of ENStar Inc. common stock to North Star shareholders whereby one share of
ENStar Inc. common stock will be issued to each holder of three shares of North
Star common stock. The adjusted weighted average shares outstanding, used to
compute pro forma income (loss) per share, was 3,217,000, 3,235,000 and
3,146,000 in 1995, 1994 and 1993.
 
     SUPPLEMENTAL DISCLOSURE OF CASH FLOW INFORMATION The Unit increased its
investment in its unconsolidated subsidiary by $70,000, $122,000 and $254,000
and operating unit equity by $42,000, $73,000 and $152,000 during 1995, 1994 and
1993, respectively, as a result of equity transactions of CorVel. In addition,
the Unit had cash payments for interest of $247,000 in 1995, $348,000 in 1994,
and $361,000 in 1993.
 
     RECENTLY ISSUED ACCOUNTING STANDARDS The Financial Accounting Standards
Board has issued two accounting standards which the Unit is required to adopt
January 1, 1996. The first statement establishes guidance on when and how to
measure impairment of long-lived assets and certain identifiable intangibles and
how to value long-lived assets to be disposed of. The second standard
establishes accounting and reporting for the impact of the fair value of
stock-based compensation plans and permits the Unit to select the fair value
based method of accounting for employee stock options or the intrinsic value
method. Upon completion of the distribution described in Note 1, management
intends to adopt the intrinsic value method of accounting and reporting for
stock-based compensation plans. Management believes the adoption of these new
accounting standards will not have a material effect on the Unit's combined
financial statements.
 
     USE OF ESTIMATES In the preparation of the Unit's combined financial
statements, management is required to make estimates and assumptions that affect
the reported amounts of assets and liabilities and related revenues and
expenses. Actual results could differ from the estimates used by management.

NOTE 3 -- RESTRUCTURING CHARGES
 
     In December 1993, Americable implemented a restructuring plan involving the
closure of its Canadian facilities, operated by Adanac Cable, Ltd., and
consolidation of its Canadian sales and customer support activities within its
U.S. operations. This plan was completed in 1994. In connection with this
consolidation, Americable recorded a restructuring charge of approximately $1.9
million in 1993. This charge includes approximately $600,000 for the write-off
of goodwill and other noncurrent assets, $700,000 for the reassessment of the
carrying value of inventory and receivables, and $600,000 for lease and
severance obligations and other related expenses.
 
NOTE 4 -- INVESTMENT IN UNCONSOLIDATED SUBSIDIARY
 
     The Unit's unconsolidated subsidiary consists of its investment in CorVel,
a health care services company. CorVel has a fiscal year end of March 31. The
following is summarized unaudited balance sheet information of CorVel as of

December 31, 1995, the fair value of the Operating Unit's investment in CorVel,
based on the closing market price, was approximately $46.7 million.
 
NOTE 5 -- NET ASSETS HELD FOR SALE
 
     In March 1991, the Unit announced its intention to sell its remaining
non-computer related manufacturing company, Eagle. The Unit has recorded the net
assets related to this subsidiary in the balance sheet under the caption "Net
Assets Held For Sale." Operating results of this subsidiary are not material.
 
NOTE 6 -- NOTES PAYABLE AND LONG-TERM DEBT
 
     Americable and Transition maintain a revolving line of credit and term loan
facility which provides borrowings up to $5.5 million due in May 1996.
Borrowings under this facility are based on eligible accounts receivable and
inventory with interest at prime plus 1.5% (10% at December 31, 1995). Amounts
outstanding under the revolving line of credit at December 31, 1995 are
classified within notes payable to the bank. The term loan bears interest at
10.665% and is payable in monthly principal installments of $36,000 with a final
installment of $893,000 due in May 1996. The credit agreement includes certain
restrictive covenants including minimum net worth requirements, limitations on
additional indebtedness and minimum interest coverage. At December 31, 1995,
Americable and Transition were in compliance with the covenants of this

     To the extent the Unit's financial reporting basis in its investment in
unconsolidated subsidiaries exceeds its tax basis, and is not expected to be
realized in a tax-free manner, the Unit records a deferred income tax liability.
At December 31, 1995, the deferred tax liability includes the initial tax effect
of $1.8 million for the difference in the financial reporting and tax basis of
the Unit's investment in CorVel following its initial public offering along with
income taxes recorded on the equity in earnings of CorVel of $794,000 in 1995,
$664,000 in 1994, and $497,000 in 1993.
 
     The tax effects of the cumulative temporary differences resulting in the
net deferred tax liability at December 31, are as follows (in thousands):

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS
 
Board of Directors and Shareholders of North Star Universal, Inc.
 
     We have audited the accompanying combined statements of operating unit
assets and liabilities of ENStar ("the Unit"), (an operating unit of North Star
Universal, Inc.), as of December 31, 1995 and 1994, and the related combined
statements of operating unit net income, operating unit equity, and cash flows
for each of the three years in the period ended December 31, 1995. These
financial statements are the responsibility of the Unit's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe our audits provide a reasonable basis for our opinion.
 
     In our opinion, the combined financial statements referred to above present
fairly, in all material respects, the combined operating unit assets and
liabilities of ENStar as of December 31, 1995 and 1994, and the combined results
of their operations and their combined cash flows for each of the three years in
the period ended December 31, 1995, in conformity with generally accepted
accounting principles.

                              W I T N E S S E T H:
 
     WHEREAS, the Boards of Directors of Michael and NSU have determined that it
is in the best interests of Michael and NSU and their respective shareholders to
consummate the merger (the "Merger") of Merger Sub, a newly-formed subsidiary of
NSU, with and into Michael with Michael as the surviving corporation;
 
     WHEREAS, Michael and NSU desire that the Merger be made on the terms and
subject to the conditions set forth in this Agreement and qualify as a
reorganization within the meaning of Section 368(a) of the Internal Revenue Code
of 1986, as amended;
 
     WHEREAS, as a condition of the Merger, Michael requires that NSU distribute
and NSU is willing to distribute immediately after the Merger to NSU
shareholders of record prior to the Merger, all of the capital stock of a newly
incorporated wholly owned subsidiary, to which, prior to the Merger, all of the
assets of NSU will be assigned, contributed or otherwise transferred other than
(i) the shares of Merger Sub, (ii) the shares of Michael Common Stock (defined
below) owned by NSU on the date hereof, (iii) cash held by NSU, and (iv) certain
other assets as the parties mutually agree, and that NSU be released from, or
mutually acceptable adequate provisions be made for, all liabilities and
obligations other than as mutually agreed by the parties, so that, after giving
effect to the Merger and such distribution, the business and operations of NSU
after the Merger will be the business and operations of Michael;
 
     WHEREAS, the distribution contemplated by the previous WHEREAS clause will
be made in accordance with the Distribution Agreement (as defined below);
 
     WHEREAS, as a further condition of the Merger, Michael requires and NSU is
willing to reduce the number of outstanding shares of NSU Common Stock (as
defined below) to an amount equal to the number of shares of Michael Common
Stock owned by NSU less a number of shares determined by formula to reflect the
amount of the liabilities retained by NSU at the time of the Merger net of the
cash retained by NSU at the time of the Merger; and
 
     WHEREAS, Michael is requiring such reduction in the number of outstanding
shares of NSU Common Stock so that each share of Michael Common Stock will be
exchangeable for one share of the Surviving Corporation Common Stock (as defined
below) after the Merger.

certificates and cash are hereinafter referred to as the "Exchange Fund") to be
issued or paid by the Surviving Corporation pursuant to Articles 1 and 2 in
connection with the Merger and the Reverse Stock Split. As provided in the
Distribution Agreement, the certificates evidencing the Spinco Common Stock
shall have been deposited by NSU with the transfer agent of NSU on or prior to
the Effective Date, for distribution on the Distribution Date in accordance with
the terms of the Distribution Agreement and the terms hereof. After the

date, tender to the Exchange Agent as an addition to the Exchange Fund all
dividends and other distributions applicable to certificates held in the
Exchange Fund for shares of the Surviving Corporation Common Stock issuable in
respect of the NSU Common Stock subject to the Reverse Stock Split.
 
     (d) Until outstanding certificates representing NSU Common Stock subject to
the Reverse Stock Split are surrendered as provided in Section 2.4(b) hereof, no
dividend or distribution payable to such holders of record of NSU Common Stock,
except the Spinco Common Stock payable in connection with the Distribution,
shall be paid to any holder of such outstanding certificates, but upon surrender
of such outstanding certificates by such holder there shall be paid to such
holder the amount of any dividends or distributions (without interest)
theretofore paid with respect to the whole shares of the Surviving Corporation
Common Stock into which such shares are converted as a result of the Reverse
Stock Split, but not paid to such holder, and which dividends or distributions
had a record date occurring subsequent to the Effective Date.

<PAGE>   120
 
     (e) After the Effective Date, there shall be no further registration of
transfers on the records of Michael of outstanding certificates formerly
representing shares of Michael Common Stock at the Effective Date (other than
the shares of the Merger Sub which are converted into Michael Common Stock
pursuant to Section 2.3(c)) and there shall be no further registration of
transfers on the records of the Surviving Corporation of outstanding
certificates representing shares of NSU Common Stock subject to the Reverse
Stock Split. If any such certificate is presented to Michael or the Surviving
Corporation, it shall be forwarded to the Exchange Agent for cancellation and
exchange for certificates representing shares of the Surviving Corporation
Common Stock as herein provided.
 
     (f) All shares of the Surviving Corporation Common Stock issued upon the
surrender for exchange of Michael Common Stock in accordance with the above
terms and conditions shall be deemed to have been issued and paid in full
satisfaction of all rights pertaining to such shares of Michael Common Stock.
All shares of the Surviving Corporation Common Stock issued upon the surrender
for exchange of NSU Common Stock subject to the Reverse Stock Split in
accordance with the above terms and conditions shall be deemed to have been
issued in full satisfaction of all rights pertaining to such shares of NSU
Common Stock.
 
     (g) Any portion of the Exchange Fund (including the proceeds of any
investments thereof, any shares of the Surviving Corporation Common Stock and
any dividends or distributions thereon) that remains unclaimed by the holders of
Michael Common Stock or NSU Common Stock subject to the Reverse Stock Split, as
the case may be, for six months after the Effective Date shall be returned or
repaid to the Surviving Corporation. Any holders of Michael Common Stock or NSU
Common Stock subject to the Reverse Stock Split who have not theretofore
complied with this Section 2.4 shall thereafter look only to the Surviving
Corporation for issuance of their shares of the Surviving Corporation Common
Stock, cash in lieu of fractional shares and any unpaid dividends and
distributions on the Surviving Corporation Common Stock deliverable in respect
of the shares of NSU Common Stock subject to the Reverse Stock Split that such
holder holds as determined pursuant to this Agreement, in each case, without any
interest thereon. If outstanding certificates for shares of Michael Common Stock
or NSU Common Stock subject to the Reverse Stock Split are not surrendered or
the payment for them not claimed prior to the date on which such payments would
otherwise escheat to or become the property of any governmental unit or agency,
the unclaimed items shall, to the extent not prohibited by abandoned property
and any other applicable law, become the property of the Surviving Corporation
(and to the extent not in its possession shall be paid over to it), free and
clear of all claims or interest of any person previously entitled to such
claims. Notwithstanding the foregoing, none of Surviving Corporation, Michael,
NSU, the Exchange Agent or any other person shall be liable to any former holder
of Michael Common Stock or NSU Common Stock subject to the Reverse Stock Split
for any amount delivered to a public official pursuant to applicable abandoned
property, escheat or similar laws.
 
     (h) In the event any certificate for Michael Common Stock or NSU Common
Stock subject to the Reverse Stock Split shall have been lost, stolen or
destroyed, the Exchange Agent shall issue and pay in exchange for such lost,
stolen or destroyed certificate, upon the making of an affidavit of that fact by
the holder thereof, such shares of the Surviving Corporation Common Stock and
cash for fractional shares, if any, as may be required pursuant to this
Agreement; provided, however, that the Surviving Corporation, in its discretion
and as a condition precedent to the issuance and payment thereof, may require
the owner of such lost, stolen or destroyed certificate to deliver a bond in
such sum as it may direct as indemnity against any claim that may be made
against the Surviving Corporation, Michael, NSU, the Exchange Agent or any other
party with respect to the certificate alleged to have been lost, stolen or
destroyed.

     (b) Michael shall furnish such information concerning Michael and the
Michael Subsidiaries as is necessary in order to cause the Prospectus/Proxy
Statement, insofar as it relates to Michael, the Michael Subsidiaries and
Michael securities, to be prepared in accordance with Section 6.4(a). Michael
agrees promptly to advise NSU if at any time prior to the Michael or NSU

<PAGE>   128
 
the earliest practicable date. NSU agrees to provide Michael with reasonable
opportunity to review and comment on the Registration Statement and any
amendment thereto before filing with the SEC or any other governmental entity
and agrees not to make such filing if Michael reasonably objects to the
completeness or accuracy of any information contained therein. Michael
authorizes NSU to utilize in the Registration Statement the information
concerning Michael, the Michael Subsidiaries and Michael securities provided to
NSU for the purpose of inclusion in the Prospectus/Proxy Statement. NSU shall
advise Michael promptly when the Registration Statement has become effective and
of any supplements or amendments thereto, and NSU shall furnish Michael with
copies of all such documents. Prior to the Effective Date or the termination of
this Agreement, each party shall consult with the other with respect to any
material (other than the Prospectus/Proxy Statement) that might constitute a
"prospectus" relating to the Merger within the meaning of the Securities Act.
 
     (e) Michael shall use reasonable efforts to cause to be delivered to NSU a
letter relating to the financial statements of Michael included in the
Registration Statement from Grant Thornton LLP, Michael's independent auditors,
dated a date within two business days before the date on which the Registration

reasonably satisfactory to NSU and customary in scope and substance for letters
delivered by independent public accountants in connection with registration
statements similar to the Registration Statement.
 
     (f) NSU shall use reasonable efforts to cause to be delivered to Michael a

expenses in connection with the Registration Statement.
 
     6.5 Accounting and Tax Treatment. Neither NSU nor Michael, nor Surviving
Corporation after the Effective Date, shall, directly or indirectly, voluntarily
take any action which would disqualify the Merger, the Reverse Stock Split and
the Distribution as a business combination utilizing the reverse acquisition
concept with Michael being the accounting acquiror for accounting purposes and
the Merger as a "reorganization" that would be tax free to the shareholders of
NSU and Michael pursuant to Section 368(a) of the Code.
 
     6.6 Michael Stock Plans. At or prior to the Effective Time, NSU shall take
all corporate action necessary to authorize and reserve for issuance a
sufficient number of shares of the Surviving Corporation Common Stock, equal to
the number of shares of Michael Common Stock reserved for issuance under the
Michael Stock Plans to be adopted and assumed by the Surviving Corporation at
the Effective Time, including the shares issuable upon exercise of the
Continuing Options, in accordance with Section 2.2(b).
 
     6.7 Press Releases. Michael and NSU shall agree with each other as to the
form and substance of any press release related to this Agreement or the

contained herein shall prohibit either party, following notification to the
other party, from making any disclosure which is required by law or regulation.

insurance for claims asserted after the Effective Date against any person who
was an officer or director of NSU or any NSU Subsidiary prior to the Effective
Date which claims relate to the period prior to the Effective Date. If such
coverage is available, NSU will, prior to the Effective Date, select which
coverage it prefers and purchase or reimburse Michael for the cost of such
coverage.

Date within two days after the date such reports or other documents are filed
with the SEC. Upon delivery of any such report or document, the delivering party
shall be deemed to have made the representations to the receiving party with
respect thereto as set forth in Sections 3.4 and 4.4, respectively.

(b) such other date(s) as mutually agreed by NSU and Michael, but such mutually
agreed date(s) shall not be later than forty-five (45) days after the
effectiveness of the Registration Statement. The Board of Directors of each of
Michael and NSU shall recommend approval of this Agreement and the Merger, and,
in the case of NSU, the New Articles, the Reverse Stock Split and the
Distribution, and use all reasonable efforts (including, without limitation,
soliciting proxies for such approvals) to obtain approvals thereof from its
shareholders, provided, however, the Board of Directors of either may fail to
make the recommendation, and/or to seek to obtain the shareholder approval
referred to in this sentence, or withdraw, modify or change any such
recommendation, if such Board of Directors determines, after consultation with
counsel, that the making of such recommendation, the seeking to obtain such
shareholder approval, or the failure to so withdraw, modify or change its
recommendation, is reasonably likely to constitute a breach of the fiduciary or
legal obligations of such Board of Directors.
 
     6.12 No Solicitation.
 
     (a) Unless and until this Agreement shall have been terminated pursuant to

other than the Michael Common Stock owned by NSU; provided that NSU may engage
in such discussion in response to an unsolicited proposal from an unrelated
party if the Board of Directors of NSU determines, after consultation with
counsel, that the failure to engage in such discussions is reasonably likely to
constitute a breach of the fiduciary or legal obligations of the Board of
Directors of NSU. NSU will promptly advise Michael if it receives a proposal or
inquiry with respect to the matters described above.
 
     (b) Unless and until this Agreement shall have been terminated pursuant to

Michael is the surviving corporation in such transaction, and (ii) the
shareholders of Michael immediately preceding such transaction will own at least
51% of the outstanding shares of Michael after giving effect to such
transaction; provided that Michael may engage in such discussion in response to
an unsolicited proposal from an unrelated party if the Board of Directors of
Michael determines, after consultation with counsel, that the failure to engage
in such discussions is reasonably likely to constitute a breach of the fiduciary
or legal obligations of the Board of Directors of Michael. Michael will promptly
advise NSU if it receives a proposal or inquiry with respect to the matters
described above.
 
     6.13 Failure to Fulfill Conditions. In the event that either of the parties

     (a) Each party shall give prompt notice to the other party of (i) the
occurrence or failure to occur of any event or the discovery of any information,
which occurrence, failure or discovery would be likely to cause any
representation or warranty on its part contained in this Agreement to be untrue,
inaccurate or incomplete after the date hereof in any material respect or, in
the case of any representation or warranty given as of a specific date, would be
likely to cause any such representation or warranty on its part contained in
this Agreement to be untrue, inaccurate or incomplete in any material respect as
of such specific date, and (ii) any material failure of such party to comply
with or satisfy any covenant or agreement to be complied with or satisfied by it
hereunder.
 
     (b) From time to time after the date hereof and prior to the Effective

and warranties which apply to the period after the date hereof by delivering an
updated Schedule to the other party pursuant to this Section 6.19(b) with
respect to any matter hereafter arising which would render any such
representation or warranty after the date of this Agreement materially untrue,
inaccurate or incomplete as a result of such matter arising. Such supplement or
amendment to a party's representations and warranties contained in an updated
Schedule delivered pursuant to this Section 6.19(b) shall be deemed to have
modified the representations and warranties of the disclosing party, and no such
supplement or amendment, or the information contained in such updated Schedule,
shall constitute a breach of a representation or warranty of the disclosing
party; provided that no such supplement or amendment may cure any breach of a
covenant or agreement of any party under Articles 5 or 6. Within fifteen (15)
days after receipt of such supplement or amendment, the receiving party may
terminate this Agreement pursuant to Section 7.1(g) hereof if (i) the
information in such supplement or amendment together with the information in any
and all of the supplements or amendments previously provided by the

reasonably likely to suffer a Material Adverse Effect or, in the case of an
updated Schedule 4.12 is, in Michael's reasonable determination a material
liability, and (ii) the disclosing party has not cured the matters giving rise
to such termination within fifteen (15) days after the receiving party notifies
the disclosing party that it is exercising its right to terminate this Agreement
under this Section 6.19(b).
 
     6.20 Notification of Anticipated NSU Net Indebtedness. No later than thirty
(30) days after the initial filing of the Registration Statement, NSU shall
notify Michael of the anticipated amount of the NSU Indebtedness at the

amount of the Dissenting Shares Holdback will be an amount within the range of
(i) the Anticipated NSU Net Indebtedness less $2,000,000, and (ii) the
Anticipated NSU Net Indebtedness plus $2,000,000.

          (i) The formation of Merger Sub and the merger of Merger Sub into

     distribution, or a transaction that has the effect of such a distribution,

     income will be recognized under such Sections by any of the stockholders of

Adverse Effect on NSU. NSU shall in all material respects have performed each
obligation and agreement and complied with each covenant to be performed and
complied with by it hereunder at or prior to the Effective Date.
 
     (b) Officers' Certificate. NSU shall have furnished to Michael a

the transactions contemplated hereby and thereby were taken, (ii) certificates

     (e) Accounting Matters. No event shall have occurred which, in the
reasonable opinion of Michael and concurred in by Grant Thornton LLP, would

generally accepted accounting principles.
 
     (f) Fairness Opinion. Within five days prior to mailing the
Prospectus/Proxy Statement to the shareholders of Michael, Michael shall have
received a written opinion in a form reasonably acceptable to Michael from Piper

Michael.

Merger, this Agreement, the New Articles, the Reverse Stock Split or the
Distribution, (iv) by NSU pursuant to Section 8.1(e), (v) by Michael pursuant to

condition under Section 7.2(a), (b) or (c), (iii) by Michael or NSU pursuant to

Merger and this Agreement, (iv) by Michael pursuant to Section 8.1(f), (v) by

written demand from NSU, Michael shall pay to NSU an amount equal to the out of
pocket expenses incurred by NSU in connection with the transactions contemplated
by this Agreement, including but not limited to the fees and expenses of NSU's
attorneys, accountants and investment banker, up to an aggregate of $500,000,

benefit. Any such extension or waiver shall only be effective if made in writing
and duly executed by the party giving such extension or waiver.

                                   ARTICLE 10
                               DISPUTE RESOLUTION
 
     10.1 Mediation and Binding Arbitration. If a dispute arises between NSU and
Michael as to the interpretation of this Agreement or any other agreement
entered into pursuant hereto, NSU and Michael agree to use the following
procedures, in lieu of either party pursuing other available remedies and as the
sole remedy, to resolve the dispute.
 
     10.2 Initiation. A party seeking to initiate the procedures shall give
written notice to the other party, describing briefly the nature of the dispute.
A meeting shall be held between the parties within 10 days of the receipt of
such notice, attended by individuals with decision-making authority regarding
the dispute, to attempt in good faith to negotiate a resolution of the dispute.
 
     10.3 Submission to Mediation. If, within 30 days after such meeting, the
parties have not succeeded in negotiating a resolution of the dispute, they
agree to submit the dispute to mediation in accordance with the Center for
Public Resources Model ADR Procedure -- Mediation of Business Disputes, as
modified herein, and to bear equally the costs of the mediation.
 
     10.4 Selection of Mediator. The parties will jointly appoint a mutually
acceptable mediator, seeking assistance in such regard from the Center for
Public Resources or another mutually agreed-upon organization if they have been
unable to agree upon such appointment within 20 days from the conclusion of the
negotiation period.
 
     10.5 Mediation and Arbitration. The parties agree to participate in good
faith in the mediation and negotiations related thereto for a period of 30 days
following the initial mediation session. If the parties are not successful in
resolving the dispute through the mediation by the end of such 30-day period,
then the parties agree to submit the matter to binding arbitration in accordance
with the Center for Public Resources Rules for Non-Administered Arbitration of
Business Disputes, as modified herein, by a panel of three arbitrators, in
Minneapolis, Minnesota, selected in accordance with the provisions of Section
10.6 hereof. The arbitration shall be governed by the Rules of the American
Arbitration Association then in effect and as modified herein, and judgment upon
the award rendered by the arbitrator may be entered by any court having
jurisdiction thereof. The arbitrators shall not, under any circumstances, have
any authority to award punitive, exemplary or
 
                                      I-26
<PAGE>   138
 
similar damages and may not, in any event, make any ruling, finding or award
that does not conform to the terms and conditions of this Agreement. Nothing
contained in this Article 10 shall limit or restrict in any way the right or
power of a party at anytime to seek injunctive relief in any court and to
litigate the issues relevant to such request for injunctive relief before such
court (i) to restrain the other party from breaching this Agreement or (ii) for
specific enforcement of this Article 10. The parties agree that any legal remedy
available to a party with respect to a breach of this Article 10 will not be
adequate and that, in addition to all other legal remedies, each party is
entitled to an order specifically enforcing this Article 10.
 
     10.6 Selection of Arbitrators. The parties shall have 10 days from the end
of the mediation period to agree upon mutually acceptable neutral persons not
affiliated with either of the parties to act as arbitrators. If the panel of
arbitrators has not been selected within such time, the parties agree jointly to
request the Center for Public Resources or another mutually agreed-upon
organization to supply within 10 days a list of potential arbitrators with
qualifications as specified by the parties in the joint request. Within five
days of receipt of the list, the parties shall independently rank the proposed
candidates, shall simultaneously exchange rankings, and shall select as the
arbitrator the individual receiving the highest combined ranking who is
available to serve. Neither party nor the arbitrators may disclose the existence
or results of any arbitration under this Agreement or any evidence presented
during the course of arbitration without the prior consent of both parties,
except as required to fulfill applicable disclosure and reporting requirements,
or as otherwise required by law.
 
     10.7 Cost of Arbitration. Each party shall bear its own costs incurred in
the arbitration. If either party refuses to submit to arbitration any dispute
required to be submitted to arbitration pursuant to this Article 10, and instead
commences any other proceeding, including litigation, then the party who seeks
enforcement of the obligation to arbitrate shall be entitled to its attorneys'
fees and costs incurred in any such proceeding.
 
     IN WITNESS WHEREOF, NSU and Michael have caused this Agreement to be
executed on the date first written above by their respective officers.

                    REORGANIZATION AND RELATED TRANSACTIONS
 
     Section 2.01 Sequence of Events. It is the intention of the parties hereto
that the transactions contemplated by this Article II shall, to the extent
practicable, be effected in the order in which such transactions are set forth
in this Article II.
 
     Section 2.02 Transfers of Assets; Assumption of Liabilities. (a) Subject to
the terms and conditions of this Agreement, effective at the start of business
on the Transfer Effective Date:
 
          (i) NSU shall contribute and transfer to Spinco or a Spinco
     Subsidiary, as appropriate, all of NSU's right, title and interest in and
     to all of the NSU Transferred Assets.
 
          (ii) NSU shall assign and transfer, and Spinco shall assume, all of
     NSU's rights, benefits and Liabilities arising pursuant to and under all
     contracts, agreements, real and personal property leases, licenses,
     instruments, arrangements and commitments (collectively, "Contracts")
     entered into or made by NSU prior to the Merger Effective Date, other than#
     the Contracts relating to the NSU Assumed Liabilities (the "Assumed
     Contracts"); provided, however, that no Assumed Contract shall be assigned
     contrary to law or the terms of such Assumed Contract and, with respect to
     the Assumed Contracts that cannot be assigned or novated to Spinco on the
     Transfer Effective Date, the performance obligations of NSU thereunder
     shall, unless not permitted by such Assumed Contract, be subcontracted or
     subleased to Spinco until such Assumed Contract has been fully performed by
     Spinco or assigned or novated. NSU and Spinco shall use reasonable efforts
     to obtain all necessary consents and Spinco shall take all necessary
     actions to perform and complete all Assumed Contracts in accordance with
     their terms even if neither assignment, novation, subcontracting nor
     subleasing is permitted by the other party. As provided in Article V
     hereof, Spinco shall indemnify NSU from and against any Liabilities under
     the Assumed Contracts. NSU covenants and agrees that it shall promptly pay
     over to Spinco any amounts received by NSU after the Transfer Effective
     Date as a result of the performance by Spinco of any of the Assumed
     Contracts.
 
          (iii) Spinco shall assume and agrees to pay, perform or discharge all
     the NSU Transferred Liabilities.
 
     (b) Whether or not all of the NSU Transferred Assets or the NSU Transferred
Liabilities shall have been legally transferred to Spinco as of the Transfer
Effective Date, NSU and Spinco agree that, as of the Transfer Effective Date,
Spinco shall have, and shall be deemed to have acquired, complete and sole
beneficial ownership over all the NSU Transferred Assets together with all of
NSU's rights, powers and privileges incident thereto, and shall be deemed to
have assumed the NSU Transferred Liabilities and all of NSU's duties,
obligations and responsibilities incident thereto.
 
     Section 2.03 Elimination of Intercompany Accounts. All intercompany
receivables, payables and loans in existence as of the Merger Effective Date
between NSU, on the one hand, and any NSU Subsidiary, on the other hand (other
than accounts, if any, relating to intercompany contractual or other obligations
which are to survive the Distribution as provided herein) shall be eliminated,
as of the Merger Effective Date, without the transfer of cash, by dividend or
capital contributions, as appropriate.
 
     Section 2.04 Transfers Not Effected At or Prior to the Distribution;
Transfers Deemed Effective as of the Distribution Date. To the extent that any
transfers and assumptions contemplated by this Article II shall not have been
consummated on or prior to the Transfer Effective Date, the parties shall
cooperate to effect such transfers and assumptions as promptly following the
Transfer Effective Date as shall be practicable, it nonetheless being agreed and
understood by the parties that no party shall be liable in any manner to any
other party for any failure of any of the transfers contemplated by this Article
II to be consummated prior to the Transfer Effective Date and that this Section
2.04 shall in no way affect the indemnification obligations of the parties
pursuant to Article V. Subject to the provisions of Section 3.02, nothing herein
shall be deemed to require the transfer of any assets or the assumption of any
Liabilities which by their terms or by operation of law cannot be transferred or
assumed; provided that Spinco shall indemnify NSU against all NSU Transferred
 
                                       C-5

Liabilities pursuant to Section 5.01. In the event that any such transfer of the
NSU Transferred Assets (other than capital stock of corporations to be
transferred hereunder) or assumption of the NSU Transferred Liabilities has not
been consummated, effective as of and after the Transfer Effective Date (i) NSU
shall thereafter hold such assets for the benefit of Spinco (at the expense of
Spinco) and retain any such Liabilities for the account of Spinco, and take such
other action as may be reasonably requested by Spinco, at Spinco's expense, in
order to place such party, insofar as reasonably possible, in the same position
as would have existed had such asset or Liability been transferred as of the
Transfer Effective Date, (ii) NSU shall, at Spinco's expense, continue to be
bound under any agreements relating to the NSU Transferred Assets or NSU
Transferred Liabilities that cannot be so transferred, and (iii) unless not
permitted by law, Spinco shall pay, perform and discharge fully all obligations
of NSU thereunder from and after the Transfer Effective Date and indemnify NSU
for all indemnifiable losses arising out of such performance by Spinco pursuant
to the provisions of Article V hereto. NSU shall, without further consideration
therefor, pay and remit to Spinco promptly all monies, rights and other
considerations received in respect of any such performance. NSU shall exercise
its rights and options under any such agreements relating to the NSU Transferred
Assets or NSU Transferred Liabilities only as reasonably directed by Spinco, and
at Spinco's expense. As and when any such asset or liability becomes
transferable, such transfer shall be effected forthwith. Notwithstanding the
foregoing, the parties shall use their best efforts to obtain all consents and
approvals, to enter into all amendatory agreements and to make all filings and
applications which may be required for the consummation of the transactions
contemplated by this Agreement, including, without limitation, all applicable
regulatory filings or consents under federal or state environmental laws.
 
     Section 2.05 No Representations or Warranties. Spinco understands and
agrees that NSU is not, in this Agreement or in any other agreement or document
contemplated by this Agreement or otherwise, representing or warranting in any
way (i) as to the value or freedom from encumbrance of, or any other matter
concerning, any NSU Transferred Assets or (ii) as to the legal sufficiency to
convey title to any such assets or the execution, delivery and filing of this
Agreement, including, without limitation, any Conveyancing or Assumption
Instruments, it being agreed and understood that all such assets are being
transferred AS IS, WHERE IS, and that the party to which such assets are to be
transferred hereunder shall bear the economic and legal risk that any
conveyances of such assets shall prove to be insufficient or that Spinco or any
of its Subsidiaries' title to any such assets shall be other than good and
marketable and free from encumbrances. Similarly, each party hereto understands
and agrees that no party hereto is, in this Agreement or in any other agreement
or document contemplated by this Agreement or otherwise, representing or
warranting in any way that the obtaining of any consents or approvals, the
execution and delivery of any amendatory agreements and the making of any
filings or applications contemplated by this Agreement will satisfy the
provisions of any or all applicable agreements or the requirements of any or all
applicable laws or judgments, it being agreed and understood that the party to
which any assets are transferred shall bear the economic and legal risk that any
necessary consents or approvals are not obtained or that any requirements of
laws or judgments are not complied with.
 
     Section 2.06 Conveyancing and Assumption Instruments. In connection with
the transfers of the NSU Transferred Assets other than capital stock and the
assumptions of the NSU Transferred Liabilities contemplated by this Agreement,
the parties shall execute or cause to be executed by the appropriate entities
the Conveyancing and Assumption Instruments in such forms as the parties shall
agree. The transfer of capital stock shall be effected by means of delivery of
stock certificates and executed stock powers and notation on the stock record
books of the corporation.
 
     Section 2.07 Tax Treatment. During the two year period following the Merger
Effective Date, NSU shall not, nor shall it permit Michael to do any of the
following, and neither of them has any plan or intention to:
 
          (a) liquidate Michael;
 
          (b) merge Michael with or into another corporation, unless Michael is
     the surviving corporation and the merger is not treated for tax purposes as
     a sale or other disposition of Michael common stock;
 
                                       C-6
<PAGE>   151
 
          (c) sell any shares of Michael Common Stock or cause Michael to issue
     any of shares of Michael Common Stock to any party other than NSU; or
 
          (d) sell any assets of NSU to any third party not otherwise an
     affiliate of the foregoing, except for (i) sales in the ordinary course of
     business or (ii) sales of assets if, after giving effect to such sales,
     Michael will retain at least 90% of the fair market value of its gross
     assets in active trades or businesses within the meaning of Section 355 of
     the Code.
 
provided, however, NSU or Michael may undertake any of the actions listed above
if (i) Spinco consents thereto or (ii) NSU obtains either a tax opinion or a
favorable private letter ruling from the Internal Revenue Service, in each case
reasonably satisfactory to Spinco, to the effect that the actions to be
undertaken would not adversely affect the tax free nature of the Merger or the
Distribution to all of the parties thereto. The shareholders of record of NSU on
the Record Date shall be third party beneficiaries of the provisions of this
Section 2.07.
 
                                  ARTICLE III
 
                                THE DISTRIBUTION
 
     Section 3.01 Cooperation Prior to the Distribution. Prior to the Merger
Effective Date:
 
     (a) NSU and Spinco shall prepare and shall use all reasonable efforts to
cause the Registration Statement to become effective under the Securities Act.
Once declared effective under the Securities Act, NSU shall mail to the holders
of NSU Common Stock the prospectus included in the Registration Statement, which
shall set forth appropriate disclosure concerning Spinco, the Distribution and
other matters. NSU and Spinco shall also prepare, and Spinco shall file with the
Commission, a Form 8 -A, to register the Spinco Common Stock under the Exchange
Act. NSU and Spinco shall use all reasonable efforts to cause the Form 8-A to
become effective under the Exchange Act.
 
     (b) NSU and Spinco shall cooperate in preparing, filing with the Commission
and causing to become effective any registration statements or amendments
thereof which are appropriate to reflect the establishment of, or amendments to,
any employee benefit and other plans contemplated by Article VI.
 
     (c) NSU and Spinco shall take all such action as may be necessary or
appropriate under the securities or blue sky laws of states or other political
subdivisions of the United States in connection with the Distribution and the
other transactions contemplated by this Agreement.
 
     (d) NSU and Spinco shall prepare, and Spinco shall file and pursue, an
application to permit listing of the Spinco Common Stock on the NASDAQ National
Market.
 
     Section 3.02 NSU Board Action; Conditions Precedent to the
Distribution. The NSU Board shall, in its discretion, establish the Record Date,
the Transfer Effective Date and the Distribution Date (which shall be the same
as the Merger Effective Date) and any appropriate procedures in connection with
the Distribution. The Distribution is expressly conditioned on the prior
consummation of the Merger. Additionally, in no event shall the Distribution
occur (i) if at the Distribution Date NSU shall not have received an opinion of
tax counsel or a private letter ruling from the IRS to the effect that the
Distribution will qualify as a tax-free spin-off under Section 355 of the Code,
and (ii) unless prior to such time the following conditions shall have been
satisfied or waived by the parties hereto:
 
     (a) the transactions contemplated by Sections 2.02 hereof, shall have been
consummated in all material respects;
 
     (b) the Spinco Common Stock shall have been approved for quotation on the
NASDAQ National Market or listing on a national securities exchange, subject to
official notice of issuance;
 
     (c) the Spinco Board, comprised as contemplated by Section 8.01, shall have
been elected by NSU, as sole shareholder of Spinco, and the Spinco Charter and
Spinco ByLaws shall have been adopted and shall be in effect;
 
                                       C-7
<PAGE>   152
 
     (d) the Registration Statement shall have been declared effective by the
Commission and the Form 8-A relating to the shares of Spinco Common Stock to be
distributed in the Distribution shall have become effective under the Exchange
Act; and
 
     (e) all conditions precedent to the obligations of NSU and Michael under
the Merger Agreement (other than consummation of the Distribution) shall have
been satisfied or waived and the Merger shall have been consummated.
 
The satisfaction or waiver of such conditions shall create an obligation on the
part of NSU to effect the Distribution on the Distribution Date.
 
     Section 3.03 The Distribution. On or prior to the Distribution Date, NSU
shall deliver to the Agent the certificate for all of the outstanding shares of
Spinco Common Stock which are owned by NSU. On the Distribution Date, after the
Effective Time of the Merger, NSU shall deliver to the Agent an instruction to
distribute as promptly as practicable following the Distribution Date to each
holder of record of NSU Common Stock on the Record Date stock certificates
evidencing such number of shares of Spinco Common Stock equal to the product of
the Exchange Ratio times the number of shares of NSU Common Stock held of record
by such holder on the Record Date and cash in lieu of any fractional share of
Spinco Common Stock obtained in the manner provided in Section 3.04 hereof. If
the number of outstanding shares of Spinco Common Stock exceeds the amount to be
distributed in the Distribution, then the remaining shares shall be deemed to
have been contributed by NSU to the capital of Spinco and retired and canceled.
Spinco agrees to provide to the Agent sufficient certificates in such
denominations as the Agent may request in order to effect the Distribution. All
of the shares of Spinco Common Stock issued in the Distribution shall be fully
paid, nonassessable and free of preemptive rights. The Distribution shall, for
all purposes under this Agreement, be deemed to have been effected at the time
NSU delivers to the Agent the instruction directing the Agent to distribute the
certificates evidencing Spinco Common Stock and cash in lieu of fractional
shares.
 
     Section 3.04 Fractional Shares. No certificate or scrip representing
fractional shares of Spinco Common Stock shall be issued as part of the
Distribution, and in lieu of receiving fractional shares each holder of NSU
Common Stock who would otherwise be entitled to receive a fractional share of
Spinco Common Stock pursuant to the Distribution will receive cash for such
fractional share. NSU and Spinco agree that NSU shall instruct the Agent to
determine the number of whole shares and fractional shares of Spinco Common
Stock allocable to each holder of record of NSU Common Stock as of the Record
Date, to aggregate all such fractional shares into whole shares and sell the
whole shares obtained thereby in the open market pursuant to Rule 236 under the
Securities Act, if available, at then prevailing prices on behalf of holders who
otherwise would be entitled to receive fractional share interests and to
distribute to each such holder such holder's ratable share of the total proceeds
of such sale. Spinco shall bear the costs of commissions incurred in connection
with such sale. If the Agent is unable to sell such shares in the open market
pursuant to Rule 236, Spinco will pay to such holders of NSU Common Stock in
lieu of any fractional share or amount of cash determined by multiplying (a) the
average closing price per share of Spinco Common Stock on the NASDAQ National
Market during the five days following the Distribution Date times (b) the
fractional share interest to which such holder would otherwise be entitled.

                 SPINCO ASSUMPTION OF CERTAIN NSU INDEBTEDNESS
 
     Section 4.01 Assumption of Certain NSU Indebtedness. Spinco and NSU shall,
on or prior to the Distribution Date, to the extent required under any indenture
with respect to any of the outstanding debentures or any of the outstanding
subordinated extendable or fixed time certificates, execute and deliver
supplemental indentures or other agreements or instruments evidencing Spinco's
assumption of NSU's obligations with respect to such outstanding debentures and
subordinated extendable and fixed time certificates; provided, however, that as
provided herein, and as contemplated by the Merger Agreement, as between NSU and
Spinco, the NSU Indebtedness is not an NSU Transferred Liability and NSU shall
be responsible for the payment in full, in accordance with the terms thereof of
all of the NSU Indebtedness and
 
                                       C-8
<PAGE>   153
 
shall indemnify, pursuant to Section 5.02 of this Agreement, Spinco for any and
all Liabilities with respect to the NSU Indebtedness.

     Section 5.03 Procedure for Indemnification.
 
     (a) The Spinco Indemnified Parties or the NSU Indemnified Parties (each
referred to hereinafter as an "Indemnified Party"), as the case may be, shall
promptly give notice to the indemnifying party hereunder (the "Indemnifying
Party") after obtaining knowledge of any claim, demand or request for payment
against any Indemnified Party for any Liabilities indemnifiable hereunder and
shall permit the Indemnifying Party to pay or assume the defense of such
Liability, and any litigation arising from such Liability. Notwithstanding the
foregoing notice requirement, the right to indemnification hereunder shall not
be affected by the failure of the party seeking indemnification to give such
notice or any delay by such party in giving such notice unless, and only to the
extent that, the rights and remedies of the Indemnifying Party shall have been
prejudiced as a result of the failure to give, or the delay in giving, such
notice. The failure by an Indemnifying Party to notify the Indemnified Party of
its election to defend any such Liability within ten (10) days after notice
thereof shall have been given to the Indemnifying Party, shall be deemed a
waiver by the Indemnifying Party of its right to defend such Liability.
 
     (b) If an Indemnifying Party assumes the defense of any Liability and any
litigation that results from such Liability, then the obligations of the
Indemnifying Party as to such litigation shall include employing counsel
reasonably satisfactory to the Indemnified Party, taking all steps necessary in
the defense or settlement of such litigation and holding the Indemnified Party
harmless from and against any and all claims and expenses caused by or arising
out of any settlement approved by the Indemnified Party or any judgment in
connection with such litigation. Without the prior written consent of the
Indemnified Party, the Indemnifying Parties shall not, in the defense of any
such litigation, consent to the entry of any judgment or enter into any
settlement that does not include as an unconditional term thereof, the giving by
the claimant or the plaintiff to the Indemnified Party of a full release, in
form reasonably satisfactory to the Indemnified Party, from all liability in
respect of such litigation. The Indemnified Party shall be entitled to
participate in the defense of any litigation at its own expense. If the
defendants in any such action include both the Indemnified Party and the
Indemnifying Party and the Indemnified Party shall have reasonably concluded
that there may be legal defenses available to it which are different from or
additional to those available to the Indemnifying Party, the Indemnified Party
shall have the right, at the expense of the Indemnifying Party, to select
separate counsel reasonably satisfactory to the Indemnifying Party to assume
such additional legal defenses, and to otherwise participate in the defense of
such action on behalf of the Indemnified Party.
 
     (c) If the Indemnifying Party does not assume the defense of any Liability
within ten (10) days after the Indemnified Party gives notice thereof to the
Indemnifying Party, then the Indemnified Party may defend against such Liability
and any litigation with respect thereto, in such manner as it deems appropriate
and the Indemnified Party may settle any such litigation on such terms as it
deems appropriate and the Indemnifying Party shall, in accordance with the
provisions of Sections 5.01 or 5.02, as the case may be, reimburse the
Indemnified Party for the amount of such settlement and for all losses and
expenses, including attorney's fees, incurred by the Indemnified Party in
connection with the defense of such Liability.
 
     (d) The Indemnified Party and the Indemnifying Party agree to cooperate
with each other in resolving or attempting to resolve any claim as to which
indemnification is sought under this Agreement and will permit the other party
access to all books and records which might be useful for such purpose during
normal business hours and at the place where such books and records are normally
kept. The Indemnified Party and the Indemnifying Party further agree to make
available, at reasonable times, such of their respective employees, officers and
agents who may have knowledge of matters relating to any claim arising out of
this agreement for the purpose of providing testimony or assisting in the
preparation or prosecution of a defense to any claim by a third party as to
which indemnification is sought under this Agreement.
 
     (e) Any dispute arising between the parties hereto as to the obligations
under this Article V shall be resolved pursuant to Article X hereto. If there is
no dispute with respect to any payment under this Article V from an Indemnifying
party to an Indemnified Party, then within ten (10) days after written demand
for such payment by the Indemnified Party, the Indemnifying Party shall pay to
the Indemnified Party the amount of any loss, expense, damage or other payment
suffered, incurred or made by the Indemnified Party against which the
Indemnified Party is indemnified by the Indemnifying Party under this Article V.
In the event the
 
                                      C-10
<PAGE>   155
 
Indemnifying Party fails to pay such undisputed amount within said ten (10) day
period, or it is determined pursuant to the provisions of Article X that the
Indemnifying Party is obligated to pay an amount which it had previously
disputed, the Indemnified Party shall be entitled to collect the following from
the Indemnifying Party: (i) interest from the date of the Indemnified Party's
demand for payment on the amount owing to the Indemnified Party at the rate
equal to the reference rate as publicly announced from time to time by First
Bank National Association plus two (2) percentage points, compounded monthly,
until the full amount owing, including any interest, has been paid in full with
all payments being applied first against accrued and unpaid interest, and (ii)
all costs and expenses, including reasonable attorneys fees, incurred by the
Indemnified Party in collecting the amounts owing from the Indemnifying Party
under this Article V.
 
     Section 5.04 Set-Off Rights. If and when, as a result of the net operating
loss carryforwards properly allocable to NSU from all Tax periods prior to or
ending on the Merger Effective Date, NSU unconditionally realizes a benefit in
the form of a reduction in the federal or state income Taxes which NSU would
otherwise be obligated to pay, Spinco may set-off the amount of any such Tax
savings against any Liability of Spinco under this Agreement (including the
indemnification obligations under Section 5.01) or, in the event Spinco has
already made payments pursuant to its indemnification obligations hereunder, NSU
will reimburse Spinco for payments previously made by Spinco to or on behalf of
an NSU Indemnified Party with respect to its obligations under this Agreement.
The benefit shall not be finally and unconditionally determined for any year
until such year is closed for any future adjustment of federal income Tax
liability. Any amount set-off by Spinco or reimbursed to Spinco by NSU hereunder
shall bear interest from and after the date that such benefit was reflected on
the consolidated Tax return of NSU or taken into account in an NSU estimated Tax
payment to the date of such off-set or reimbursement at the rate of 6% per
annum. NSU shall promptly provide Spinco notice of each and every time it has
filed a Tax report or return wherein it has claimed or used such Tax benefit.

                             EMPLOYEE BENEFIT PLANS
 
     Section 6.01 The 401(k) Savings Plan. (a) As soon as practicable after the
date hereof (i) effective as of the Merger Effective Date, Spinco shall assume
and be solely responsible for, all Liabilities of NSU under the [NORTH STAR
UNIVERSAL 401(K) SAVINGS PLAN] (the "Savings Plan") and (ii) prior to the Merger
Effective Date, NSU agrees to take such actions as may be necessary in order for
Spinco or a Subsidiary of Spinco effectively to maintain and administer such

actions as may be necessary or appropriate in order to establish Spinco or a
Subsidiary of Spinco as successor to NSU as to all rights, assets, duties and
Liabilities of NSU under, or with respect to, the Savings Plan, including, but
not limited to, the rights, assets, duties and Liabilities of NSU under, or with
respect to, any and all trust agreements to the extent that they relate solely
to the Savings Plan. Any action taken by NSU pursuant to this Section 6.01 after
the Merger Effective Date shall be at Spinco's expense.
 
     (b) Upon Spinco or a Subsidiary of Spinco becoming the successor employer
or successor plan sponsor to NSU or any of its subsidiaries under the Savings
Plan, NSU agrees to take such actions as may be necessary to amend any trust
agreement required to be amended in order for Spinco or a Subsidiary of Spinco
effectively to assume and administer the Savings Plan.
 
     (c) Transfers pursuant to this Section 6.01 shall be effected, where
practicable, so as to preserve each plan participant's investment election.
 
     (d) NSU and Spinco shall, in connection with the transfers described in
this Section 6.01, cooperate in making all appropriate filings required under
the Code or ERISA, and the regulations thereunder and any applicable securities
laws, and take all such action as may be necessary and appropriate to cause such
transfers to take place as soon as practicable after the Distribution Date.
 
     (e) From and after the Merger Effective Date, NSU and its Subsidiaries
thereafter shall cease to have any liability or obligation whatsoever with

dental, life insurance, health, accident, disability or other welfare benefit
plans in existence on or prior to the Merger Effective Date and from and after

and life insurance benefits) made by or in respect of (i) any Spinco Employee or
(ii) any employee of NSU prior to the Merger Effective Date who shall have
retired or whose employment otherwise terminates on or before the Merger
Effective Date, regardless of whether such claim shall relate to events which
occurred prior or subsequent to the Merger Effective Date. Spinco shall also
assume all "COBRA" continuation Liabilities of NSU as of the Merger Effective
Date.
 
     (c) Prior to the Merger Effective Date, NSU and Spinco shall take all
actions necessary and appropriate to effect the assumption of the NSU welfare

otherwise necessary to assume the Liabilities which are or shall become the
responsibility of Spinco under this Section 6.02.
 
     Section 6.03 NSU Employees. Effective as of the Merger Effective Date,
Spinco agrees to assume the employment of all employees of NSU who have not
resigned or been terminated on or prior to such date. Spinco shall assume and be
solely responsible for all Liabilities in connection with claims made by or on
behalf of such NSU employees in respect of salary, benefits, severance pay,

termination or alleged termination of the employment of any such person,
regardless of whether such termination or alleged termination occurred prior to
or subsequent to the Merger Effective Date.

Date, employees of NSU, relating to any employee liability or obligation not
otherwise provided for in this Agreement.
 
     Section 6.05 Preservation of Rights To Amend or Terminate Plans. No
provisions of this Agreement shall be construed as a limitation on the right of
Spinco or any Spinco Subsidiary to amend such plan or terminate its
participation therein which Spinco or any Spinco Subsidiary would otherwise have
under the terms of such plan or otherwise, and no provision of this Agreement
shall be construed to create a right in any employee or beneficiary of such
employee under a plan which such employee or beneficiary would not otherwise
have under the terms of the plan itself.

                                  TAX MATTERS
 
     Section 7.01 Allocation of Items of Income or Deduction for Reporting
Purposes. NSU, in consultation with and subject to the approval of Spinco, shall
either (i) cause Spinco to close its permanent books and records (including work
papers) as of the Distribution Date, in accordance with Treasury Regulations
Section 1.1502-76(b)(2) in order to permit Spinco's taxable income for the
taxable period ending on the Distribution Date to be reported and determined on
the basis of income shown on its permanent books and records (including work
papers) or (ii) allocate items of income or deduction between tax periods ending
on or before the Distribution Date and tax periods beginning after the
Distribution Date in accordance with Treasury Regulations Section
1.1502-76(b)(2)(ii).
 
     Section 7.02 Spinco Indemnification for Tax Periods Prior to Distribution
Date. Spinco agrees to indemnify and hold harmless NSU from and against any
liability for Taxes attributable to NSU or Spinco
 
                                      C-12

(specifically including for all purposes of this Article VII, Taxes attributable
to all NSU Transferred Assets and NSU Transferred Liabilities transferred
pursuant to Article II) for Tax periods or portions thereof ending on or before
the Distribution Date. For purposes of this Section 7.02, "Spinco" shall mean
Spinco, itself, as well as all of its Subsidiaries eligible to be included in a
consolidated federal income tax return filed by Spinco as the common parent,
including any Subsidiary owned by NSU prior to the Merger Effective Date but not
then owned by NSU, and "NSU" shall mean NSU, itself, as well as all of its
Subsidiaries eligible to be included in a consolidated federal income tax return
filed by NSU as the common parent.
 
     Section 7.03 NSU Liable for Filing and Payment of Spinco's Taxes Prior to
Distribution Date. NSU, in consultation with and subject to the approval of
Spinco, shall, at Spinco's expense, file (or shall cause to be filed) all tax
returns of Spinco for tax periods ending on or before the Distribution Date. NSU
shall, to the extent permissible, include (or cause to be included) the results
of the operations of Spinco in NSU's consolidated federal tax return and in any
other consolidated, unitary, or combined tax return for tax periods ending on or
before the Distribution Date and shall, subject to the indemnification
obligations under Section 7.02, pay all Taxes due for such periods with respect
to Spinco.
 
     Section 7.04 Spinco Liable for Filing and Payment of Its Own Taxes for Tax
Periods Beginning Prior to Distribution Date and Ending After Distribution
Date. Spinco shall file (or shall cause to be filed) all Tax returns of Spinco
for any Tax period which begins before the Distribution Date and ends on or
after the Distribution Date. Spinco shall also file (or shall cause to be filed)
all Tax returns of Spinco for all subsequent Tax periods. Accordingly, Spinco
shall pay all Taxes shown as due on such returns or ultimately determined to be
due with respect to such periods and shall be entitled to keep and retain for
itself any refunds of Taxes or credits paid on behalf of or made available to
it. All Tax returns and any schedules to be included therewith for the Tax
period which begins before the Distribution Date and ends after the Distribution
Date shall be prepared on a basis consistent with those prepared for prior Tax
periods and consistent with the method used by NSU to allocate items of Spinco's
income or deduction for the Tax period ending on the Distribution Date pursuant
to Section 7.01 hereof, and shall be subject to the approval of NSU prior to
being filed by Spinco, which approval shall not be unreasonably withheld.
 
     Section 7.05 Spinco's Right to Make Section 172(b)(3) Election and
Qualified Right to Subsequent Refund. Spinco shall have the right and option to
make an election pursuant to Section 172(b)(3) of the Code to carry forward any
of its net operating losses incurred in tax periods beginning after the
Distribution Date which, if carried back, would be carried back to a tax period
ending on or before the Distribution Date. Notwithstanding the foregoing,
whether or not Spinco makes such an election, Spinco shall be entitled to any
and all tax refunds, whether received by NSU or Spinco, that result from a
carryback of net operating losses or credits of Spinco arising in a tax period
beginning after the Distribution Date to a tax period ending on or before the
Distribution Date.
 
     Section 7.06 Scope of NSU's Power to Negotiate Settlement During Audit for
Periods after the Merger Effective Date. In the event that any Taxing authority
conducts an audit to determine the amount of any net operating loss
carryforwards of NSU as of the Merger Effective Date for any Tax period
beginning after the Distribution Date, NSU shall notify Spinco and allow Spinco
to participate with NSU in contesting such issue and each party shall pay its
own expenses relating to the contesting of such issue. Notwithstanding the
foregoing, NSU shall have the right to finally resolve such issue.
 
     Section 7.07 Rights of Parties With Respect to an Asserted Tax
Liability. Promptly after receipt by NSU of a written notice of any demand,
claim or circumstance, including any Tax audit, which, after the lapse of time,
would or might give rise to a claim or commencement of any action, proceeding,
or investigation with respect to which indemnity may be sought under Section
7.02 hereof (an "Asserted Tax Liability"), NSU shall give written notice thereof
to Spinco (the "Tax Claim Notice"). The Tax Claim Notice shall contain factual
information (to the extent known to NSU) describing in reasonable detail the
Asserted Tax Liability and shall include copies of any notice or other document
received from any taxing authority in respect of such Asserted Tax Liability. If
NSU fails to give Spinco prompt notice of an Asserted Tax Liability as required
by this Section 7.07, and if such failure results in an irrevocable financial
detriment to Spinco, then any amount which Spinco is otherwise required to pay
NSU pursuant to Section 7.02 hereof with respect to such Asserted
 
                                      C-13
<PAGE>   158
 
Tax Liability shall be reduced by the amount of such irrevocable financial
detriment. Spinco may elect to direct, through counsel of its own choosing
reasonably acceptable to NSU and at its own expense, the compromise or contest,
either administratively or in the courts, of any Asserted Tax Liability. If
Spinco elects to direct the compromise or contest of any Asserted Tax Liability,
it shall, either within 30 calendar days after receiving the Tax Claim Notice
with respect to such Asserted Tax Liability (or sooner, if the nature of the
Asserted Tax Liability so requires) notify NSU of its intent to do so, and NSU
shall cooperate at its own expense in the compromise or contest of such Asserted
Tax Liability. Spinco, at its discretion, may enter into a settlement agreement
with respect to, or otherwise resolve, any Asserted Tax Liability without the
express consent of NSU, unless such settlement affects the Tax returns of NSU
after the Merger Effective Date, in which case the consent of NSU shall be
required and shall not be unreasonably withheld. If Spinco (1) within 30
calendar days after receiving the Tax Claim Notice with respect to such Asserted
Tax Liability (or sooner, if the nature of the Asserted Tax Liability so
requires) notifies NSU that it has elected not to direct the compromise or
contest of the Asserted Tax Liability, or (2) fails to properly notify NSU
within such period of its election to direct or not to direct the compromise or
contest of the Asserted Tax Liability, NSU may pay, compromise, or contest at
its own expense and in its sole discretion such Asserted Tax Liability. If NSU
or Spinco elects to direct the compromise or contest of any liability for Taxes
as provided herein, the other party shall promptly empower (by power of attorney
and such other documentation as may be appropriate) such representative of the
empowered party as the empowered party may designate to represent the empowering
party in any audit, claim for refund or administrative or judicial proceeding
insofar as such audit, claim for refund or proceeding involves an asserted
liability for Taxes for which Spinco would be liable under Section 7.02 hereof.
For all purposes of this Section 7.07, the right to participate in all
proceedings either administratively or in the courts relating to an Asserted Tax
Liability shall include the right to attend and be kept fully informed of all of
the foregoing but shall not include, unless expressly provided for herein, the
power to compromise, contest or make any other decisions with respect to an
Asserted Tax Liability.
 
     Section 7.08 Mutual Duty to Cooperate and Act in Good Faith With Respect to
Filing or Amending of Returns, Claiming Refunds, or Conducting Audit. NSU and
Spinco shall provide each other with such cooperation and information as either
reasonably may request of the other in filing any tax return, amended return, or
claim for refund, in determining a liability for Taxes or a right to a refund of
Taxes, or in conducting any audit or proceeding in respect of Taxes. Such
cooperation and information shall include providing copies of relevant tax
returns or portions thereof, together with accompanying schedules and related
work papers and documents relating to rulings or other determinations by tax
authorities. Each party shall make its employees available on a mutually
convenient basis to provide explanation of any documents or information provided
hereunder. NSU shall make available to Spinco, with respect to all tax years in
which Spinco was includable in NSU's affiliated group (as defined in Section
1504 of the Code) copies of all work papers and schedules relating to the
preparation of Spinco's pro forma federal and state income tax returns which
were included in NSU's federal consolidated and state income tax returns which
are necessary to reconcile such pro forma returns with the amounts actually
included in such consolidated returns. NSU and Spinco shall make available to
each other all other books and records relating to Taxes of Spinco with respect
to all tax years in which Spinco was includable in NSU's affiliated group (as
defined in Section 1504 of the Code). NSU and Spinco agree to maintain and
preserve for a period of eight (8) years after the period to which such
documents relate, and, upon written request, to provide to the other party, such
factual information as that party reasonably requires for filing tax returns,
tax planning, and contesting any tax audit that only NSU or Spinco, as the case
may be, actually possesses.

periods:
 
          (i) $9,000,000 during the period beginning on the Merger Effective
     Date and continuing to the later to occur of (x) the Release Date or (y)

generally accepted accounting principles, except that securities owned by Spinco
which are publicly traded shall be valued at their market value without any
adjustment for lack of liquidity or control premium, but reduced for any taxes
payable on the disposition of such securities, taking into account any and all
tax benefits (e.g., net operating loss carryforward, tax credits, deductions or
exclusions) available to Spinco and using Spinco's then applicable effective tax
rate for purposes of such calculations.
 
     Section 8.04 Adjustment for Dissenting Shares Liability. If the actual
amount paid after the Merger Effective Date with respect to the Dissenting
Shares (the "Actual Payment") is less than the Dissenting Shares Holdback, then
within ten days after the date of determination of the Actual Payment, NSU shall
pay to Spinco by wire transfer of immediately available funds to a designated
account the amount of such shortfall. Notwithstanding anything herein or in the
Merger Agreement to the contrary, with respect to the Dissenting Shares and the
Dissenting Shares Liability, NSU agrees that it shall promptly give notice to
Spinco after obtaining knowledge of any threatened or pending claim regarding
the Dissenting Shares or the Dissenting Shares Liability and Spinco shall, at
its expense, assume and direct the negotiation, settlement or defense of such
claim and any litigation arising from such claim, and NSU agrees to cooperate
with Spinco in resolving or attempting to resolve any such claim or litigation;
provided that Spinco shall not, without NSU's prior

<PAGE>   160
 
consent, settle any such claim after the Merger Effective Date if such
settlement may result in the Dissenting Shares Liability exceeding the
Dissenting Shares Holdback.

Merger Effective Date, all such repayments (excluding any payments made with
respect to any instruments that have matured or otherwise become due and payable
in accordance with their respective terms prior to such repayment date) to be
effected on or about the same date.

give written notice to the other party, describing briefly the nature of the
dispute. A meeting shall be held between the parties within 10 days of the
receipt of such notice, attended by individuals with decision-making authority
regarding the dispute, to attempt in good faith to negotiate a resolution of the
dispute.

<PAGE>   162
 
restrict in any way the right or power of a party at any time to seek injunctive
relief in any court and to litigate the issues relevant to such request for
injunctive relief before such court (i) to restrain the other party from
breaching this Agreement or (ii) for specific enforcement of this Article X. The
parties agree that any legal remedy available to a party with respect to a
breach of this Article X will not be adequate and that, in addition to all other
legal remedies, each party is entitled to an order specifically enforcing this
Article X.
 
     Section 10.06 Selection of Arbitrators. The parties shall have 10 days from
the end of the mediation period to agree upon mutually acceptable neutral

panel of arbitrators has not been selected within such time, the parties agree
jointly to request the Center for Public Resources or another mutually
agreed-upon organization to supply within 10 days a list of potential
arbitrators with qualifications as specified by the parties in the joint
request. Within five days of receipt of the list, the parties shall
independently rank the proposed candidates, shall simultaneously exchange
rankings, and shall select as the arbitrator the individual receiving the
highest combined ranking who is available to serve. Neither party nor the

prior consent of both parties, except as required to fulfill applicable
disclosure and reporting requirements, or as otherwise required by law.
 
     Section 10.07 Cost of Arbitration. Each party shall bear its own costs
incurred in the arbitration. If either party refuses to submit to arbitration

who seeks enforcement of the obligation to arbitrate shall be entitled to its
attorneys' fees and costs incurred in any such proceeding.

             ORDERLY DISPOSITION AND REGISTRATION RIGHTS AGREEMENT
 
     This Agreement made and entered into this      day of December, 1995, by
and between NORTH STAR UNIVERSAL, INC., a Minnesota corporation, which, upon the

     WITNESSETH:
 
     WHEREAS, Michael Minnesota is a party to an Agreement and Plan of
Reorganization dated December   , 1995 (the "Merger Agreement") providing for
the merger (the "Merger") of NSU Merger Co. ("Merger Sub"), a newly formed
Delaware corporation and wholly-owned subsidiary of Michael Minnesota, with and
into Michael Foods, Inc., a Delaware corporation ("Michael"), as the surviving
corporation; and
 
     WHEREAS, under Section 6.16 of the Merger Agreement, Michael Minnesota
agreed to execute and deliver and to cause the Michael Shareholders to execute
and deliver this Orderly Disposition and Registration Rights Agreement.
 
     NOW THEREFORE, IN CONSIDERATION of the premises and of the terms and
conditions hereinafter set forth, the parties agree as follows:
 
     1. Definitions. Unless the context otherwise requires or unless otherwise
defined in this agreement, capitalized terms shall have the meanings ascribed to
them in the Merger Agreement. Any references to Michael Minnesota shall include
North Star Universal, Inc. and Michael Minnesota from and after the consummation
of the Merger and the change of its name to Michael Foods, Inc.
 
     2. Actions Pending Effective Time. From the date of this Agreement until
the Effective Time, the Michael Shareholders, individually and collectively,
shall:
 
     a. not sell or offer to sell, hypothecate or transfer any shares of Michael
Minnesota common stock, except that this limitation shall not apply to sales of
Michael Minnesota common stock made pursuant to Rule 144 of the Securities and
Exchange Commission (the "SEC"), or the pledge of Michael Minnesota common stock
to secure surety bonds for Michael-Curry Companies, Inc. or transfers of Michael
Minnesota common stock among Michael Shareholders;
 
     b. vote in favor of the Merger, the Spinoff, the Reverse Stock Split and
the election of directors nominated by Michael Minnesota management at any
meeting of shareholders duly called and held for such purposes; and
 
     c. prepare and file any pre-merger notification to the Federal Trade
Commission required in connection with the Merger under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976 and the rules of the Federal Trade Commission
thereunder.
 
     3. Restrictions Upon Disposition. For a period of twenty-four (24) months
following the Effective Date, the Michael Shareholders, individually or
collectively, shall not:
 
     a. sell or offer to sell shares of common stock of Michael Minnesota
exceeding five percent (5%) of the then outstanding shares of common stock of
Michael Minnesota to any person or group in any single
<PAGE>   169
 
transaction or series of transactions without providing to Michael Minnesota the
first right to buy such shares as provided in Section 5 below;
 
     b. sell or offer to sell any shares of common stock of Michael Minnesota to
any person or group which owns five percent (5%) or more of the outstanding
common stock of Michael Minnesota without providing to Michael Minnesota the
first right to buy such shares as provided in Section 5 below; or
 
     c. pledge, hypothecate, or encumber any shares of Michael Minnesota owned
by any of the Michael Shareholders except to secure surety bonds obtained by
Michael-Curry Companies, Inc.
 
For purposes of this agreement, the term "group" shall mean any two or more
persons who agree to act together for the purpose of acquiring, holding, voting
or disposing of common stock of Michael Minnesota.
 
     4. Shares Covered. This agreement shall apply to all shares of common stock
of Michael Minnesota which are owned by the Michael Shareholders at the date of
this agreement or which are acquired by the Michael Shareholders prior to the
Effective Date or as a result of the Merger, but shall not apply to any shares
of common stock of Michael Minnesota which are purchased or otherwise acquired
by any of the Michael Shareholders subsequent to the Effective Date unless such
shares were subject to this agreement at the time they were so acquired by a
Michael Shareholder.
 
     5. Option to Purchase. Upon the occurrence of any of the events described
in Section 3(a) or (b), the Michael Shareholders or Shareholder proposing to
sell or offer shares of common stock of Michael Minnesota shall provide written
notice thereof to Michael Minnesota and shall offer to Michael Minnesota the
right to purchase such shares. The notice shall state the number of shares
offered and the price per share and any other conditions of the proposed sale or
offer and shall include a copy of any written document setting forth the terms
of the proposed sale or offer between the Michael Shareholders and the purchaser
or offeree. Michael Minnesota shall have twenty (20) days from its receipt of
such notice within which to purchase the shares so offered. In the event Michael
Minnesota does not complete the purchase within such twenty (20) day period, the
Michael Shareholders or Shareholder sending the notice shall be permitted for a
period of thirty (30) days thereafter to sell Michael Minnesota shares equal in
number to the shares offered in such notice free of any restrictions of this
agreement at a price no less than the purchase price per share set forth in such
notice and under terms and conditions no more favorable to the purchaser than
the terms and conditions offered to Michael Minnesota in such notice.
 
     6. Tender Offer. The restrictions set forth in Section 3 and the option to
purchase granted to Michael Minnesota in Section 5 shall not apply if a tender
offer is made for all or substantially all of the outstanding Michael Minnesota
common stock and the management of Michael Minnesota does not, within seven (7)
days of the commencement of such tender offer, announce its opposition to the
tender offer. Notwithstanding the foregoing, the following additional terms and
conditions shall apply in the event of a tender offer:
 
     a. In the event that one or more of the Michael Shareholders has offered
shares to Michael Minnesota pursuant to Section 5 hereof and, prior to
acceptance of such offer by Michael Minnesota, a tender offer is made for all or
substantially all of the outstanding Michael Minnesota common stock, Michael
Minnesota shall, within twenty (20) days of the date such Michael Shareholder(s)
have made such offer, have the right to acquire the shares offered by such
Michael Shareholder(s) at the higher of the price offered by the Michael
Shareholder(s) or the tender offer price, regardless of whether Michael
Minnesota's management has announced it opposition to such tender offer.
 
     b. In the event that one or more of the Michael Shareholders has offered
shares to Michael Minnesota pursuant to Section 5 hereof and, following
acceptance of such offer by Michael Minnesota but prior to the closing of such
transaction, either a tender offer is made for all or substantially all of the
outstanding Michael Minnesota common stock or the management of Michael
Minnesota rescinds an earlier opposition to such a tender offer, Michael
Minnesota shall have the option of (a) rescinding its agreement to purchase the
shares from such Michael Shareholder(s) within two (2) days of the commencement
of such tender offer or its announcement of its rescindment of its opposition to
the tender offer; or (b) acquiring such shares at the higher of the price
offered by such Michael Shareholder(s) at the tender offer price.

<PAGE>   170
 
     7. Legend. Each of the Michael Shareholders shall forthwith deliver to the
secretary of Michael Minnesota all certificates representing shares of common
stock of Michael Minnesota which are subject to this agreement for the purpose
of placing thereon the following legend:
 
     "The shares represented by this certificate are subject to certain
     restrictions on the transfer, sale or other disposition of the shares
     pursuant to an agreement dated             , 1995 between the issuer and
     the registered owner hereof, a copy of which may be obtained from the
     secretary of the corporation."
 
The secretary shall promptly return the legended certificates to the Michael
Shareholders.
 
     8. Directors. For a period of twenty-four (24) months following the
Effective Date, the Board of Directors of Michael Minnesota shall include
representatives of the Michael Shareholders as provided below. The first board
of directors of Michael Minnesota at the Effective Date shall include Jeffrey J.
Michael and Miles E. Efron or other substitute nominees of the Michael
Shareholders if either of them are unable or unwilling to serve as
representatives of the Michael Shareholders. Within thirty (30) days following
the end of each calendar year after the Effective Date and within the
twenty-four (24) months following the Effective Date, the Michael Shareholders
shall give notice to Michael Minnesota of their nominee or nominees for Board of
Directors. If the Michael Shareholders collectively own 10% or more of the
outstanding common stock of Michael Minnesota, they shall be entitled to
nominate two (2) directors. If the Michael Shareholders own less than 10% of the
outstanding common stock of Michael Minnesota, they shall be entitled to
nominate one (1) director. Notice hereunder shall be given by Jeffrey J.
Michael, as representative of all the Michael Shareholders.
 
     9. Registration Rights.
 
     a. Piggyback Rights. If at any time within twenty-four (24) months
following the Effective Date, Michael Minnesota proposes to register common
stock under the Securities Act of 1933, as amended (the "Securities Act") in
connection with a public offering of common stock for its own account solely for
cash (other than a registration on form S-4 or S-8 or any successor form
thereof) in a manner that would permit registration of all or a portion of the
Michael Minnesota common stock owned by the Michael Shareholders, it will give
prompt notice thereof to the Michael Shareholders. Upon written notice of any
Michael Shareholders to Michael Minnesota received within fifteen (15) days
after delivery of notice of the proposed offering by Michael Minnesota, Michael
Minnesota will use its best efforts to effect the registration of the Michael
Minnesota shares covered by such notice under the Securities Act; provided,
however, that Michael Minnesota shall have the right to abandon the registration
in its entirety at any time and shall not be required to register shares of the
Michael Shareholders if the underwriters in any underwritten offering reasonably
object to the inclusion of such shares in the registration, and provided
further, that in any underwritten offering, the Michael Shareholders
participating in the registration agree to sell their shares to the underwriters
on the same terms and conditions as apply to Michael Minnesota, with such
differences as customarily apply in combined primary and secondary offerings.
 
     b. Requested Registration. If, at any time commencing on the Effective Date
and continuing for a period of twenty-four (24) months thereafter, Michael
Minnesota shall receive a written request from one or more Michael Shareholders
that Michael Minnesota effect the registration under the Securities Act of all
or a part of such Michael Shareholder's(') shares of Michael Minnesota common
stock constituting in the aggregate at least 500,000 shares (such number of
shares to be adjusted to reflect any stock split, stock dividend or other
combination or reclassification of Michael Minnesota's capital stock after the
Effective Date) and requesting that such shares be sold in a registered public
offering in accordance with this Section 9, then Michael Minnesota will, within
ten (10) days after receipt thereof, give notice to all other Michael
Shareholders of the receipt of such request and each such holder may elect by
written notice received by Michael Minnesota within ten (10) days from the date
of the notice by Michael Foods to have all or part of his shares of Michael
Minnesota common stock included in such registration; provided, however, that
the Michael Shareholders collectively shall only have the right to cause Michael
Minnesota to effect a registration pursuant to this section on two occasions
during such twenty-four (24) month period. Upon receipt of such notice, Michael
Minnesota will, as soon as practicable, use reasonable efforts to effect the
registration under the Securities Act of all registrable securities which it has
been so requested to register and provided further, that Michael
 
                                       E-3
<PAGE>   171
 
Minnesota: (i) shall not be obligated to cause any special audit to be
undertaken in connection with any such registration; (ii) shall be entitled to
postpone for a reasonable period of time, but not in excess of one hundred
twenty (120) days, the filing of any registration statement otherwise required
to be prepared pursuant to this section if Michael Minnesota is, at such time,
conducting or about to conduct an underwritten public offering of equity
securities (or securities convertible into equity securities) and is advised in
writing by its managing underwriter that such offer would, in its opinion, be
adversely effected by the registration so requested; and (iii) shall be entitled
to postpone such requested registration for up to 120 days if Michael Minnesota
determines, in view of the advisability of deferring public disclosure of
material corporate developments or other information, that such registration and
the disclosure required to be made pursuant thereto would not be in the best
interest of Michael Minnesota at such time.
 
     c. Form of Requested Registration. All registrations proposed to be
effected under this Section shall be made on Form S-3 unless the registration
shall be in connection with underwritten public offering and the managing
underwriter shall advise Michael Minnesota in writing that, in its opinion, the
use of another form of registration statement is of material importance to the
success of such proposed offering. In such case, the registration shall be
effected on such other form. During the term of this agreement, Michael
Minnesota shall take all such reasonable actions as may be necessary to maintain
its eligibility to use such form(s).
 
     d. Expenses. In connection with any registration statement pursuant to this
section and whether or not the sale of the shares is consummated, each selling
Michael Shareholder will pay: (i) a pro rata portion of the aggregate
registration expenses and other expenses incurred by Michael Minnesota in
connection with the registration of the sale of the shares and the sale of the

securities included in the registration statement at the time the registration
statement is filed with the SEC relative to the total number of securities
covered by such registration statement at such time, (ii) a pro rata portion
(based on the number of such Michael Shareholder's registrable securities
included in the registration statement at the time the registration statement is
filed with the SEC relative to the total number of securities covered by such

any underwritten offering, the effective date of the registration statement in
the case of a non-underwritten offering or upon abandonment of the registration.
 
     e. Completion. A registration requested pursuant to this section will not
be deemed to have been effected unless it has become effective under the
Securities Act, provided that, if within 180 days after it has become effective
the offering of registrable securities pursuant to such registration is
interfered with by any stop order, injunction or other order or requirement of
the SEC or other governmental agency or court, such registration will be deemed
not to have been effected.
 
     f. Selection of Underwriter and Investment Manager. If a requested

registered by the Michael Shareholder(s) hereunder, keep such registration
statement effective for one hundred eighty (180) days; (ii) prepare and file
with the SEC such amendments and supplements to such

of copies of the prospectus included in such registration statement (including

each such Michael Shareholder may reasonably request in order to facilitate the
disposition of the registrable securities by such seller but only while it shall
be required under the provisions hereof to cause the registration statement to
remain current; (iv) use its reasonable efforts to register or qualify such
registrable securities covered by such registration statement under such other
securities or blue sky laws of such jurisdictions as the sellers shall
reasonably request, except that Michael Minnesota shall not, for any purpose, be
required to qualify generally to do business as a foreign corporation in any
jurisdiction where, but for the requirements of this clause, it would not be
obligated to be so qualified, to subject itself to taxation in any such
jurisdiction, or consent to general service of process in any such jurisdiction;
(v) use its reasonable efforts to list the securities being registered on the
National Association of Securities Dealers, Inc. National Market System
("NASDAQ-NMS"), if such registrable securities are not already so listed.
 
     h. Information. Michael Minnesota may require each selling Michael
Shareholder to furnish it with such information regarding such selling Michael
Shareholder and pertinent to the disclosure requirements relating to the
registration and the distribution of such securities as Michael Minnesota may
from time to time reasonably request in writing.
 
     i. Underwriting Agreement. The selling Michael Shareholders shall execute
and deliver an underwriting agreement in customary form in connection with any
underwritten offering made pursuant to a registration hereunder.
 
     10. Indemnification and Contribution. As a condition to the registration of
registrable securities of the Michael Shareholders pursuant to this agreement,
Michael Minnesota may require the selling Michael Shareholders to enter into an
Indemnification and Contribution Agreement with respect to claims or liabilities
arising under the Securities Act or the Securities Exchange Act of 1934 as a
result of the representations and warranties made by the selling Michael
Shareholder(s) in connection with their offer or sale of the registrable
securities. Such agreement shall be in customary form and shall contain mutual
cross indemnity and contribution provisions.

enforced in accordance with the laws of the State of Minnesota without giving

corporation which is a constituent party to the proposed Merger.

                           [PIPER JAFFRAY LETTERHEAD]
 
              , 1996
 
Board of Directors
Michael Foods, Inc.
324 Park National Bank Building
5353 Wayzata Boulevard
Minneapolis, MN 55416
 
Members of the Board:
 
     This letter relates to the proposed merger of Michael Foods, Inc. ("Michael
Foods") and a newly formed merger subsidiary ("Merger Sub") of North Star
Universal, Inc. ("NSU") (the "Merger") pursuant to the Agreement and Plan of
Reorganization by and between Michael Foods, NSU and Merger Sub (the
"Agreement"). Prior to the Merger, NSU will transfer to a subsidiary ("Spinco")
all assets (other than its shares of Michael Foods and other mutually agreed
assets) and liabilities (other than $25 to $38 million of net debt (the "Debt"))
of NSU and will then spin off the shares of Spinco on a pro rata basis to the
NSU shareholders before the Merger. In connection with the Merger, NSU
shareholders will receive their pro rata share of Michael Foods stock owned by
NSU before the Merger after a portion of those shares are repurchased by Michael
Foods. The amount of shares repurchased will be equal to the amount of Debt
assumed by Michael Foods in the Merger divided by the product of the Discount
Factor (as defined in the Agreement) times the average price of Michael Foods
common stock during the twenty trading days ending the third trading day
immediately preceding the effective date of the Merger. It is our understanding,
and for purposes of this opinion we have assumed, that the Debt shall not be
less than $25,000,000 nor more than $38,000,000 and that NSU will have no
liabilities following the Merger other than liabilities assumed from Michael
Foods, the NSU Retained Liabilities (as defined in the Agreement) and
liabilities which are fully indemnified against by Spinco. In connection with
the Merger, all shares of Michael Foods common stock held by shareholders other
than NSU will be exchanged for NSU common stock. You have requested our opinion
as to the fairness to Michael Foods, from a financial point of view, of the
effective price per share that Michael Foods is paying NSU in the form of Debt
assumed (the "Consideration") for the shares of Michael Foods common stock that
it is repurchasing from NSU, and the exchange of Michael Foods common stock for
NSU common stock.
 
     Piper Jaffray Inc. ("Piper Jaffray"), as a customary part of its investment
banking business, is engaged in the valuation of businesses and their securities
in connection with mergers and acquisitions, underwritings and secondary
distributions of securities, private placements, and valuations for estate,
corporate and other purposes. Piper Jaffray makes a market in the Common Stock
of Michael Foods and also provides research coverage for Michael Foods. We acted
as comanager of public offerings of Michael Foods common stock in 1987, 1988 and
1991 and an offering of senior notes in 1989. For our services in rendering this
opinion, Michael Foods will pay us a fee and indemnify us against certain
liabilities. The fee is not contingent upon the consummation of the Merger.
 
     In arriving at our opinion, we have undertaken such reviews, analyses and
inquiries as we deemed necessary and appropriate under the circumstances. Among
other things, we have:
 
          1. Reviewed the Agreement and Plan of Reorganization by and between
     Michael Foods, NSU and Merger Sub dated December 21, 1995.
 
          2. Reviewed the annual reports, Form 10-K's and audited financial
     statements for Michael Foods for the three years ended December 31, 1994.
 
          3. Reviewed the Form 10-Q's for Michael Foods for the quarters ended
     March 31, June 30 and September 30, 1995.
<PAGE>   177
 
          4. Reviewed the annual reports, Form 10-K's and audited financial
     statements for NSU for the three years ended December 31, 1994.
 
        5. Reviewed the Form 10-Q's for NSU for the quarters ended March 31,
     June 30 and September 30, 1995.
 
        6. Reviewed two-year financial forecasts for Michael Foods furnished by
     Michael Foods management.
 
          7. Conducted discussions with members of senior management of Michael
     Foods, including the President and Chief Executive Officer, Chief Financial
     Officer and Executive Vice President and Assistant Treasurer. Topics
     discussed included, but were not limited to, the background and rationale
     for the proposed Merger, the financial condition, operating performance,
     balance sheet characteristics and prospects of Michael Foods business
     independently and the financial and operating prospects for the combined
     company after consummation of the proposed Merger.
 
          8. Conducted discussions with members of senior management of NSU,
     including the Chief Financial Officer. Topics discussed included, but were
     not limited to, the background and rationale of the proposed Merger, the
     financial condition, operating performance, and the balance sheet
     characteristics of NSU and the prospects for the combined company after
     consummation of the proposed Merger.
 
        9. Reviewed the historical prices and trading activity for Michael Foods
     common stock and NSU common stock.
 
          10. Reviewed the financial terms, to the extent publicly available, of
     certain comparable transactions which we deemed relevant.
 
          11. Considered the proforma effect of the proposed Merger on Michael
     Foods earnings per share for the two fiscal years ending December 31, 1997.
 
          12. Compared certain financial and securities data of Michael Foods
     with certain financial and securities data of companies deemed similar to
     Michael Foods or representative of the business sector in which Michael
     Foods operates.
 
          13. Reviewed such other financial data, performed such other analyses
     and considered such other information as we deemed necessary and
     appropriate under the circumstances.
 
     We have relied upon and assumed the accuracy and completeness of the
financial statements and other information provided by Michael Foods, NSU or
otherwise made available to us and have not attempted independently to verify
such information. We have further relied upon the assurances of Michael Foods'
management that the information provided pertaining to Michael Foods has been
prepared on a reasonable basis and, with respect to financial planning data,
reflects the best currently available estimates and that they are not aware of
any information or facts that would make the information provided to us
incomplete or misleading. In that regard, we have assumed with your consent that
any projections or forecasts, reflect best currently available estimates and
judgments of the Michael Foods management, and that such projections and
forecasts will be realized in the amounts and in the time periods currently
estimated by the management of Michael Foods. For the purpose of this opinion,
we have assumed that neither Michael Foods nor NSU is a party to any pending
transaction, including external financing, recapitalizations, acquisitions or
merger discussions, other than the Merger or in the ordinary course of business.
We have also assumed, with your consent, that the Merger will qualify as a
tax-free exchange.
 
     In arriving at our opinion, we have not performed any appraisals or
valuations of specific assets of Michael Foods or NSU and express no opinion
regarding the liquidation value of Michael Foods or NSU. Our opinion is
necessarily based upon information available to us, facts and circumstances and
economic, market and other conditions as they exist and are subject to
evaluation on the date hereof; events occurring after the date hereof could
materially affect the assumptions used in preparing this opinion. We have not
undertaken to reaffirm or revise this opinion or otherwise comment upon any
events occurring after the date hereof. We
 
                                      II-2
<PAGE>   178
 
express no opinion herein as to the prices at which shares of Michael Foods
common stock may trade at any future time.
 
     This opinion is for the benefit of the Board of Directors of Michael Foods
and shall not be published or otherwise used, nor shall any public references to
Piper Jaffray be made without our written consent, except for inclusion in the
full proxy/prospectus to be sent to all stockholders of Michael Foods and NSU
and in any filings or disclosures required by law. This opinion is not intended
to be and does not constitute a recommendation to any stockholder as to how such
stockholder should vote with respect to the Merger. In connection with this
opinion, we were not requested to opine as to, and this opinion does not
address, the merits of the basic business decision to proceed with or effect the
Merger.
 
     Based upon and subject to the foregoing and based upon such other factors
as we consider relevant, it is our opinion that the Consideration for the
repurchase of the Michael Foods common stock and the exchange of Michael Foods
common stock for NSU common stock is fair, from a financial point of view, to
Michael Foods.
 
Sincerely,

Board of Directors

RE: Fairness Opinion
 
Gentlemen:
 
     In connection with the proposed transaction (the "Transaction"), consisting
of the Merger together with the Spin-off as defined below, whereby Michael
Foods, Inc. ("MFI") will merge (the "Merger") into a newly organized subsidiary
of North Star Universal, Inc. (the "Company"), immediately before the
distribution (the "Spin-off") to the Company's shareholders, as constituted
prior to the merger (the "Current Shareholders"), of all of the outstanding
shares of second newly organized subsidiary of the Company ("Spinco"), you have
requested our opinion ("Opinion") as to the fairness, from a financial point of
view, of the Transaction to the Company's Current Shareholders.
 
     As a customary part of its investment banking business, Goldsmith, Agio,
Helms Securities, Inc. ("GAHS") is engaged in the valuation of businesses and
securities in connection with mergers and acquisitions, private placements, and
valuations for estate, corporate, and other purposes. GAHS does not make a
market for the Company's common stock. GAHS is a party to a separate engagement
agreement with the Company whereby GAHS is providing advisory services to the
Company with respect to the Transaction, pursuant to which GAHS contingent on
consummation of the Transaction. In return for GAHS' services in connection with
providing this Opinion, the Company will pay GAHS a fee of $100,000, twenty-five
percent of which fee is not contingent upon the consummation of the Transaction,
with the balance payable to GAHS upon closing of the Transaction. In addition,
the Company will indemnify GAHS against certain liabilities.
 
     In arriving at our opinion, we have undertaken such reviews, analyses and
inquiries as we deemed necessary and appropriate under the circumstances. Among
other things, we have reviewed the Merger Agreement, the Distribution Agreement,
and financial and other information relating to the Company and MFI. We reviewed
the reported price and trading activity of the common stock of the Company and
of MFI. We compared certain financial and stock market information with respect
to the Company and MFI with similar information for certain other companies, the
securities of which are publicly traded. We have made inquiries of the Company's
management as to the Company's financial condition, operating results, business
outlook, plans and opportunities.
 
     We have relied upon and assume the accuracy, completeness, and fairness of
the financial statements and other information of the Company, and have not
attempted independently to verify such information. We have further relied upon
assurances by the Company that the information provided to us has a reasonable
basis, and with respect to projections and other business outlook information,
reflects the best currently available estimates, and that the Company is not
aware of any information or fact that would make the information provided to us
incomplete or misleading. Our Opinion is not based on any specific appraisal of
the liquidation value of the Company, or any of its assets, or of Spinco. We are
not expressing any Opinion as to the prices at which shares of common stock of
Spinco or the Company or MFI will trade subsequent to the date of the
Transaction, and we are not expressing any Opinion as to the prices at which
shares of the Company's or MFI's common stock have traded prior to the date of
the Transaction. Our Opinion is based upon the information available to us and
the facts and circumstances as they exist and are subject to evaluation on the
date hereof; events occurring after the date hereof could materially affect the
assumptions used in preparing this Opinion. We did not actively solicit
indications of interest or value from any third parties for the Company or any
of its assets, and we did not solicit indications of interest or value from any
third parties for MFI. We
 
                                      III-1
<PAGE>   181
 
were not requested to opine, and do not opine, in any way concerning other
transactions or agreements entered into in conjunction with the Transaction.
 
     Our opinion is rendered to the Board of Directors of the Company and cannot
be relied upon by any other person, nor published or otherwise used or referred
to publicly, except as provided in our letter of engagement.
 
     Based upon and subject to the foregoing, and based upon such other facts as
we consider relevant, it is our opinion that, as of the date hereof, the
Transaction is fair to the Company's Current Shareholders from a financial point
of view.
 
                                        Sincerely,
 
                                        Goldsmith, Agio, Helms Securities Inc.

dissent from, and obtain payment for the fair value of the shareholder's shares
in the event of, any of the following corporate actions:
 
     (a) An amendment of the articles that materially and adversely affects the
rights or preferences of the shares of the dissenting shareholder in that it:
 
          (1) alters or abolishes a preferential right of the shares;
 
          (2) creates, alters, or abolishes a right in respect of the redemption
     of the shares, including a provision respecting a sinking fund for the
     redemption or repurchase of the shares;
 
          (3) alters or abolishes a preemptive right of the holder of the shares
     to acquire shares, securities other than shares, or rights to purchase
     shares or securities other than shares;
 
          (4) excludes or limits the right of a shareholder to vote on a matter,
     or to cumulate votes, except as the right may be excluded or limited
     through the authorization or issuance of securities of an existing or new
     class or series with similar or different voting rights; except that an
     amendment to the articles of an issuing public corporation that provides
     that section 302A.671 does not apply to a control share acquisition does
     not give rise to the right to obtain payment under this section;
 
     (b) A sale, lease, transfer, or other disposition of all or substantially
all of the property and assets of the corporation, but not including a
transaction permitted without shareholder approval in section 302A.661,
subdivision 1, or a disposition in dissolution described in section 302A.725,
subdivision 2, or a disposition pursuant to an order of a court, or a
disposition for cash on terms requiring that all or substantially all of the net
proceeds of disposition be distributed to the shareholders in accordance with
their respective interests within one year after the date of disposition;
 
     (c) A plan of merger, whether under this chapter or under chapter 322B, to
which the corporation is a party, except as provided in subdivision 3;
 
     (d) A plan of exchange, whether under this chapter or under chapter 322B,
to which the corporation is a party as the corporation whose shares will be
acquired by the acquiring corporation, if the shares of the shareholder are
entitled to be voted on the plan; or
 
     (e) Any other corporate action taken pursuant to a shareholder vote with
respect to which the articles, the bylaws, or a resolution approved by the board
directs that dissenting shareholders may obtain payment for their shares.
 
     SUBD. 2. BENEFICIAL OWNERS. (a) A shareholder shall not assert dissenters'
rights as to less than all of the shares registered in the name of the
shareholder, unless the shareholder dissents with respect to all the shares that
are beneficially owned by another person but registered in the name of the
shareholder and discloses the name and address of each beneficial owner on whose
behalf the shareholder dissents. In that event, the rights of the dissenter
shall be determined as if the shares as to which the shareholder has dissented
and the other shares were registered in the names of different shareholders.
 
     (b) The beneficial owner of shares who is not the shareholder may assert
dissenters' rights with respect to shares held on behalf of the beneficial
owner, and shall be treated as a dissenting shareholder under the terms of this
section and section 302A.473, if the beneficial owner submits to the corporation
at the time of or before the assertion of the rights a written consent of the
shareholder.
 
     SUBD. 3. RIGHTS NOT TO APPLY. Unless the articles, the bylaws, or a
resolution approved by the board otherwise provide, the right to obtain payment
under this section does not apply to a shareholder of the surviving corporation
in a merger, if the shares of the shareholder are not entitled to be voted on
the merger.

     SUBD. 4. OTHER RIGHTS. The shareholders of a corporation who have a right
under this section to obtain payment for their shares do not have a right at law
or in equity to have a corporate action described in subdivision 1 set aside or
rescinded, except when the corporate action is fraudulent with regard to the
complaining shareholder or the corporation.
 
302A.473. PROCEDURES FOR ASSERTING DISSENTERS' RIGHTS
 
     SUBDIVISION 1. DEFINITIONS. (a) For purposes of this section, the terms
defined in this subdivision have the meanings given them.

the corporate action referred to in section 302A.471, subdivision 1 or the
successor by merger of that issuer.
 
     (c) "Fair value of the shares" means the value of the shares of a
corporation immediately before the effective date of the corporate action

     SUBD. 2. NOTICE OF ACTION. If a corporation calls a shareholder meeting at
which any action described in section 302A.471, subdivision 1 is to be voted
upon, the notice of the meeting shall inform each shareholder of the right to
dissent and shall include a copy of section 302A.471 and this section and a
brief description of the procedure to be followed under these sections.
 
     SUBD. 3. NOTICE OF DISSENT. If the proposed action must be approved by the
shareholders, a shareholder who wishes to exercise dissenters' rights must file
with the corporation before the vote on the proposed action a written notice of
intent to demand the fair value of the shares owned by the shareholder and must
not vote the shares in favor of the proposed action.
 
     SUBD. 4. NOTICE OF PROCEDURE; DEPOSIT OF SHARES.  (a) After the proposed
action has been approved by the board and, if necessary, the shareholders, the
corporation shall send to all shareholders who have complied with subdivision 3
and to all shareholders entitled to dissent if no shareholder vote was required,
a notice that contains:
 
          (1) The address to which a demand for payment and certificates of
     certificated shares must be sent in order to obtain payment and the date by
     which they must be received;
 
          (2) Any restrictions on transfer of uncertificated shares that will
     apply after the demand for payment is received;
 
          (3) A form to be used to certify the date on which the shareholder, or
     the beneficial owner on whose behalf the shareholder dissents, acquired the
     shares or an interest in them and to demand payment; and
 
          (4) A copy of section 302A.471 and this section and a brief
     description of the procedures to be followed under these sections.
 
     (b) In order to receive the fair value of the shares, a dissenting
shareholder must demand payment and deposit certificated shares or comply with
any restrictions on transfer of uncertificated shares within 30 days after the
notice required by paragraph (a) was given, but the dissenter retains all other
rights of a shareholder until the proposed action takes effect.
 
     SUBD. 5. PAYMENT; RETURN OF SHARES. (a) After the corporate action takes
effect, or after the corporation receives a valid demand for payment, whichever
is later, the corporation shall remit to each dissenting shareholder who has
complied with subdivisions 3 and 4 the amount the corporation estimates to be
the fair value of the shares, plus interest, accompanied by:
 
          (1) The corporation's closing balance sheet and statement of income
     for a fiscal year ending not more than 16 months before the effective date
     of the corporate action, together With the latest available interim
     financial statements;
 
                                      IV-2
<PAGE>   185
 
          (2) An estimate by the corporation of the fair value of the shares and
     a brief description of the method used to reach the estimate; and
 
          (3) A copy of section 302A.471 and this section, and a brief
     description of the procedure to be followed in demanding supplemental
     payment.
 
     (b) The corporation may withhold the remittance described in paragraph (a)
from a person who was not a shareholder on the date the action dissented from
was first announced to the public or who is dissenting on behalf of a person who
was not a beneficial owner on that date. If the dissenter has complied with
subdivisions 3 and 4, the corporation shall forward to the dissenter the
materials described in paragraph (a) a statement of the reason for withholding
the remittance, and an offer to pay to the dissenter the amount listed in the
materials if the dissenter agrees to accept that amount in full satisfaction.
The dissenter may decline the offer and demand payment under subdivision 6.
Failure to do so entitles the dissenter only to the amount offered. If the
dissenter makes demand, subdivisions 7 and 8 apply.
 
     (c) If the corporation fails to remit payment within 60 days of the deposit
of certificates or the imposition of transfer restrictions on uncertificated
shares, it shall return all deposited certificates and cancel all transfer
restrictions. However, the corporation may again give notice under subdivision 4
and require deposit or restrict transfer at a later time.
 
     SUBD. 6. SUPPLEMENTAL PAYMENT; DEMAND. If a dissenter believes that the
amount remitted under subdivision 5 is less than the fair value of the shares
plus interest, the dissenter may give written notice to the corporation of the
dissenter's own estimate of the fair value of the shares, plus interest, within
30 days after the corporation mails the remittance under subdivision 5, and
demand payment of the difference. Otherwise, a dissenter is entitled only to the
amount remitted by the corporation.
 
     SUBD. 7. PETITION; DETERMINATION. If the corporation receives a demand
under subdivision 6, it shall, within 60 days after receiving the demand, either
pay to the dissenter the amount demanded or agreed to by the dissenter after
discussion with the corporation or file in court a petition requesting that the
court determine the fair value of the shares, plus interest. The petition shall
be filed in the county in which the registered office of the corporation is
located, except that a surviving foreign corporation that receives a demand
relating to the shares of a constituent domestic corporation shall file the
petition in the county in this state in which the last registered office of the
constituent corporation was located. The petition shall name as parties all
dissenters who have demanded payment under subdivision 6 and who have not
reached agreement with the corporation. The corporation shall, after filing the
petition, serve all parties with a summons and copy of the petition under the
rules of 180 civil procedure. Nonresidents of this state may be served by
registered or certified mail or by publication as provided by law. Except as
otherwise provided, the rules of civil procedure apply to this proceeding. The
jurisdiction of the court is plenary and exclusive. The court may appoint
appraisers, with powers and authorities the court deems proper, to receive
evidence on and recommend the amount of the fair value of the shares. The court
shall determine whether the shareholder or shareholders in question have fully
complied with the requirements of this section, and shall determine the fair
value of the shares, taking into account any and all factors the court finds
relevant, computed by any method or combination of methods that the court, in
its discretion, sees fit to use, whether or not used by the corporation or by a
dissenter. The fair value of the shares as determined by the court is binding on
all shareholders, wherever located. A dissenter is entitled to judgment in cash
for the amount by which the fair value of the shares as determined by the court,
plus interest, exceeds the amount, if any, remitted under subdivision 5, but
shall not be liable to the corporation for the amount, if any, by which the
amount, if any, remitted to the dissenter under subdivision 5 exceeds the fair
value of the shares as determined by the court, plus interest.
 
     SUBD. 8. COSTS; FEES; EXPENSES. (a) The court shall determine the costs and
expenses of a proceeding under subdivision 7, including the reasonable expenses
and compensation of any appraisers appointed by the court, and shall assess
those costs and expenses against the corporation, except that the court may
assess part or all of those costs and expenses against a dissenter whose action
in demanding payment under subdivision 6 is found to be arbitrary, vexatious, or
not in good faith.
 
                                      IV-3
<PAGE>   186
 
     (b) If the court finds that the corporation has failed to comply
substantially with this section, the court may assess all fees and expenses of
any experts or attorneys as the court deems equitable. These fees and expenses
may also be assessed against a person who has acted arbitrarily, vexatiously, or
not in good faith in bringing the proceeding, and may be awarded to a party
injured by those actions.
 
     (c) The court may award, in its discretion, fees and expenses to an
attorney for the dissenters out of the amount awarded to the dissenters, if any.

ITEM 20.         Indemnification of Officers and Directors.

         Minnesota Statutes Section 302A.521 provides that a corporation shall
indemnify any person made or threatened to be made a party to a proceeding by
reason of the former or present official capacity of such person against
judgments, penalties, fines (including, without limitation, excise taxes
assessed against such person with respect to any employee benefit plan),
settlements and reasonable expenses, including attorneys' fees and
disbursements, incurred by such person in connection with the proceeding, if,
with respect to the acts or omissions of such person complained of in the
proceeding, such person (1) has not been indemnified therefor by another
organization or employee benefit plan; (2) acted in good faith; (3) received no
improper personal benefit and Section 302A.255 (with respect to director
conflicts of interest), if applicable, has been satisfied; (4) in the case of a
criminal proceeding, had no reasonable cause to believe the conduct was
unlawful; and (5) reasonably believed that the conduct was in the best
interests of the corporation in the case of acts or omissions in such person's
official capacity for the corporation or reasonably believed that the conduct
was not opposed to the best interests of the corporation in the case of acts or
omissions in such person's official capacity for other affiliated
organizations. The Articles of Incorporation of ENStar provides that ENStar
shall indemnify officers and directors to the extent permitted by Section
302A.521 as now enacted or hereafter amended.

         ENStar will also maintain an insurance policy or policies to assist in
funding indemnification of directors and officers for certain liabilities.

ITEM 22.         Undertakings.

         (a)     The undersigned Registrant hereby undertakes:

         (1)     To file, during any period in which offers or sales are being
made, a post-effective amendment to this Registration Statement:

                 (i)      To include any prospectus required by Section
                          10(a)(3) of the Securities Act of 1933;

                 (ii)     To reflect in the prospectus any facts or events
                          arising after the effective date of the registration
                          statement (or the most recent post-effective
                          amendment thereof) which, individually or in the
                          aggregate, represent a fundamental change in the
                          information set forth in the registration statement;
                          and





                                      II-4
<PAGE>   191


                 (iii)    To include any material information with respect to
                          the plan of distribution not previously disclosed in
                          the registration statement or any material change to
                          such information in the registration statement;

         (2)     That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to
be a new registration statement relating to the securities offered therein, and
the offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof;

         (3)     To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

         (b)(1)  The undersigned Registrant hereby undertakes as follows:  that
prior to any public reoffering of the securities registered hereunder through
use of a prospectus which is a part of this Registration Statement, by any
person or party who is deemed to be an underwriter within the meaning of Rule
145(c), the issuer undertakes that such reoffering prospectus will contain the
information called for by the applicable registration form with respect to
reofferings by persons who may be deemed underwriters, in addition to the
information called for by the other items of the applicable form.

         (2)     The Registrant undertakes that every prospectus (i) that is
filed pursuant to paragraph (1) immediately preceding, or (ii) that purports to
meet the requirements of Section 10(a)(3) of the Securities Act of 1933 and is
used in connection with an offering of securities subject to Rule 415, will be
filed as a part of an amendment to the Registration Statement and will not be
used until such amendment is effective, and that, for purposes of determining
any liability under the Securities Act of 1933, each such post-effective
amendment shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.

         (c)     Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the foregoing provisions, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable.  In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

         (d)     The undersigned Registrant hereby undertakes to respond to
requests for information that is incorporated by reference into the Prospectus
pursuant to Items 4, 10(b), 11 or 13 of this Form, within one business day of
receipt of such request, and to send the incorporated documents by first class
mail or other equally prompt means.  This includes information contained in
documents filed subsequent to the effective date of the Registration Statement
through the date of responding to the request.

         (e)     The undersigned Registrant hereby undertakes to supply by
means of a post-effective amendment all information concerning a transaction,
and the company being acquired involved therein, that was not the subject of
and included in the Registration Statement when it became effective.

         distribution of assets of the corporation upon its liquidation,
         dissolution or winding up over one or more other classes and/or series
         of capital stock of the corporation in such amount as is set forth in
         the board resolutions establishing such class or series or as is
         determined in a manner specified in such resolutions;

                 (d) are redeemable or exchangeable at the option of the
         corporation and/or on a mandatory basis for cash, capital stock or
         indebtedness of the corporation or other property, at such times or
         upon the occurrence of such events, and at such prices, as are set
         forth in the board resolutions establishing such class or series or as
         are determined in a manner specified in such resolutions;

                 (e) are entitled to the benefits of such sinking fund, if any,
         as is required to be established by the corporation for the redemption
         and/or purchase of such shares by the board resolutions establishing
         such class or series;

                 (f) are convertible at the option of the holders thereof into
         shares of any other class or series of capital stock of the
         corporation, at such times or upon the occurrence of such events, and
         upon such terms, as are set forth in the board resolutions
         establishing such class or series or as are determined in a manner
         specified in such resolutions;





                                      -2-
<PAGE>   3


                 (g) are exchangeable at the option of the holders thereof for
         cash, capital stock or indebtedness of the corporation or other
         property, at such times or upon the occurrence of such events, and at
         such prices, as are set forth in the board resolutions establishing
         such class or series or as are determined in a manner specified in
         such resolutions;

                 (h) are entitled to such voting rights, if any, as are
         specified in the board resolutions establishing such class or series
         (including, without limiting the generality of the foregoing, the
         right to elect one or more directors voting alone as a single class or
         series or together with one or more other classes and/or series of
         Preferred Stock, if so specified by such board resolutions) at all
         times or upon the occurrence of specified events; and

                 (i) are subject to restrictions on the issuance of additional
         shares of Preferred Stock of such class or series or of any other
         class or series, or on the reissuance of shares of Preferred Stock of
         such class or series or of any other class or series, or on increases
         or decreases in the number of authorized shares of Preferred Stock of
         such class or series or of any other class or series.

Without limiting the generality of the foregoing authorizations, any of the
rights and preferences of a class or series of Preferred Stock may be made
dependent upon facts ascertainable outside the board resolutions establishing
such class or series, and may incorporate by reference some or all of the terms
of any agreements, contracts or other arrangements entered into by the
corporation in connection with the issuance of such class or series, all to the
full extent permitted by the Minnesota Business Corporation Act.  Unless
otherwise specified in the board resolutions establishing a class or series of
Preferred Stock, holders of a class or series of Preferred Stock shall not be
entitled to cumulate their votes in any election of directors in which they are
entitled to vote and shall not be entitled to any preemptive rights to acquire
shares of any class or series of capital stock of the corporation.

                        ARTICLE 4.  NO CUMULATIVE VOTING

         There shall be no cumulative voting by the shareholders of the

                 Newly created directorships resulting from any increase in the
authorized number of directors or vacancies in the board of directors resulting
from death, resignation, retirement, disqualification, removal from office or
other cause may be filled by a majority vote of the directors then in office
though less than a quorum, and directors so chosen shall hold office for a term
expiring at the next annual meeting of shareholders at which a vote is held
with respect to the class for which such director has been chosen.  No decrease
in the number of directors constituting the board of directors shall shorten
the term of any incumbent director.

                    ARTICLE 7.  WRITTEN ACTION BY DIRECTORS

the board of directors of the corporation may be taken by a written action
signed, or counterparts of a written action signed in the aggregate, by all of
the directors unless the action need not be approved by the shareholders of the
corporation, in which case the action may be taken by a written action signed,
or counterparts of a written action signed in the aggregate, by the number of
directors that would be required to take the same action at a meeting of the
board of directors of the corporation at which all of the directors were
present.

                         ARTICLE 8.  DIRECTOR LIABILITY

may be held at any time and for any purpose and may be called by the chief
executive officer, the chief financial officer, two or more directors or by a
shareholder or shareholders holding 10% or more of the voting power of all
shares entitled to vote, except that a special meeting for the purpose of
considering any action to directly or indirectly facilitate or affect a
business combination, including any action to change or otherwise affect the
composition of the board of directors for that purpose, must be called by 25%
or more of the voting power of all shares entitled to vote.  A shareholder or
shareholders holding the requisite percentage of the voting power of all shares
entitled to vote may demand a special meeting of the shareholders by written
notice of demand given to the chief executive officer or chief financial
officer of the corporation and containing the purposes of the meeting.  Within
30 days after receipt of demand by one of those officers, the board of
directors shall cause a special meeting of shareholders to be called and held
on notice no later than 90 days after receipt of the demand, at the expense of
the corporation.  Special meetings shall be held on the date and at the time
and place fixed by the chief executive officer or the board of directors,
except that a special meeting called by or at demand of a shareholder or
shareholders shall be held in the county where the principal executive office
is located.  The business transacted at a special meeting shall be limited to
the purposes as stated in the notice of the meeting.

           Section 2.04.Quorum, Adjourned Meetings.  The holders of a majority
of the shares entitled to vote shall constitute a quorum for the transaction of
business at any regular or special meeting.  In case a quorum shall not be
present at a meeting, the meeting may be adjourned from time to time without
notice other than announcement at the time of adjournment of the date, time and
place of the adjourned meeting.  If a quorum is present, a meeting may be
adjourned from time to time without notice other than announcement at the time
of adjournment of the date, time and place of the adjourned meeting.  At
adjourned meetings at which a quorum is present, any business may be transacted
which might have been transacted at the meeting as originally noticed.  If a
quorum is present when a meeting is convened, the shareholders present may
continue to transact business until adjournment notwithstanding the withdrawal
of enough shareholders originally present to leave less than a quorum.

           Section 2.05.Voting.  At each meeting of the shareholders every
shareholder having the right to vote shall be entitled to vote either in person
or by proxy.  Each shareholder, unless the articles of incorporation or
statutes provide otherwise, shall have one vote for each share having voting
power registered in such shareholder's name on the books of the corporation.
Jointly owned shares may be voted by any joint owner unless the corporation
receives written notice from any one of them denying the authority of that
person to vote those shares.  Upon the demand of any





                                      -2-

shareholder, the vote upon any question before the meeting shall be by ballot.
All questions shall be decided by a majority vote of the number of shares
entitled to vote and represented at the meeting at the time of the vote except
if otherwise required by statute, the articles of incorporation, or these
bylaws.

           Section 2.06.Record Date.  The board of directors may fix a date,
not exceeding 60 days preceding the date of any meeting of shareholders, as a
record date for the determination of the shareholders entitled to notice of,
and to vote at, such meeting, notwithstanding any transfer of shares on the
books of the corporation after any record date so fixed.  If the board of
directors fails to fix a record date for determination of the shareholders
entitled to notice of, and to vote at, any meeting of shareholders, the record
date shall be the 20th day preceding the date of such meeting.

           Section 2.07.Notice of Meetings.  There shall be mailed to each
shareholder, shown by the books of the corporation to be a holder of record of
voting shares, at his or her address as shown by the books of the corporation,
a notice setting out the time and place of each regular meeting and each
special meeting, except (unless otherwise provided in section 2.04 hereof)
where the meeting is an adjourned meeting and the date, time and place of the
meeting were announced at the time of adjournment, which notice shall be mailed
at least five days prior thereto (unless otherwise provided in section 2.04
hereof); except that notice of a meeting at which a plan of merger or exchange
is to be considered shall be mailed to all shareholders of record, whether
entitled to vote or not, at least fourteen days prior thereto.  Every notice of
any special meeting called pursuant to section 2.03 hereof shall state the
purpose or purposes for which the meeting has been called, and the business
transacted at all special meetings shall be confined to the purposes stated in
the notice.  The written notice of any meeting at which a plan of merger or
exchange is to be considered shall so state such as a purpose of the meeting.
A copy or short description of the plan of merger or exchange shall be included
in or enclosed with such notice.

           Section 2.08.Waiver of Notice.  Notice of any regular or special
meeting may be waived by any shareholder either before, at or after such
meeting orally or in writing signed by such shareholder or a representative
entitled to vote the shares of such shareholder.  A shareholder, by his or her
attendance at any meeting of shareholders, shall be deemed to have waived
notice of such meeting, except where the shareholder objects at the beginning
of the meeting to the transaction of business because the meeting is not
lawfully called or convened, or objects before a vote on an item of business
because the item may not lawfully be considered at that meeting and does not
participate in the consideration of the item at that meeting.

organizational meeting of the board of directors, the number of directors shall
be the number named in the articles of incorporation.  Thereafter, the number
of directors shall be increased or decreased from time to time by resolution of
the board of directors or the shareholders.  Directors need not be
shareholders.  Each of the directors shall hold office until the regular
meeting of shareholders next held after such director's election and until such
director's successor shall have been elected and shall qualify, or until the
earlier death, resignation, removal, or disqualification of such director.

           Section 3.03.Board Meetings.  Meetings of the board of directors may

directors may be called by the chairman of the board by giving at least
twenty-four hours' notice, or by any other director by giving at least five
days' notice, of the date, time and place thereof to each director by mail,
telephone, telegram or in person.  If the day or date, time and place of a
meeting of the board of directors has been announced at a previous meeting of
the board, no notice is required.  Notice of an adjourned meeting of the board
of directors need not be given other than by announcement at the meeting at
which adjournment is taken.

           Section 3.05.Waiver of Notice.  Notice of any meeting of the board
of directors may be waived by any director either before, at, or after such
meeting orally or in a writing signed by such director.  A director, by his or
her attendance at any meeting of the board of directors, shall be deemed to
have waived notice of such meeting, except where the director objects at the
beginning of the meeting to the transaction of business because the meeting is
not lawfully called or convened and does not participate thereafter in the
meeting.

immediately prior to a meeting of the board of directors shall constitute a
quorum for the transaction of business at such meeting.

           Section 3.07.Absent Directors.  A director may give advance written
consent or opposition to a proposal to be acted on at a meeting of the board of
directors.  If such director is not present at the meeting, consent or
opposition to a proposal does not constitute presence for purposes of
determining the existence of a quorum, but consent or opposition shall be
counted as a vote in favor of or against the proposal and shall be entered in
the minutes or other record of action at the meeting, if the proposal acted on
at the meeting is substantially the same or has substantially the same effect
as the proposal to which the director has consented or objected.

           Section 3.08.Conference Communications.  Any or all directors may
participate in any meeting of the board of directors, or of any duly
constituted committee thereof, by any means of communication through which the
directors may simultaneously hear each other during such meeting.  For the
purposes of establishing a quorum and taking any action at the meeting, such
directors participating pursuant to this section 3.08 shall be deemed present
in person at the meeting; and the place of the meeting shall be the place of
origination of the conference telephone conversation or other comparable
communication technique.

           Section 3.09.Vacancies; Newly Created Directorships.  Vacancies on
the board of directors of this corporation occurring by reason of death,
resignation, removal or disqualification shall be filled for the unexpired term
by a majority of the remaining directors of the board although less than a
quorum; newly created directorships resulting from an increase in the
authorized number of directors by action of the board of directors as permitted
by section 3.02 may be filled by a majority vote of the directors serving at
the time of such increase; and each director elected pursuant to this section
3.09 shall be a director until such director's successor is elected by the
shareholders at their next regular or special meeting.

           Section 3.10.Removal.  Any or all of the directors may be removed

shareholders holding a majority of the shares entitled to vote at an election
of directors except, as otherwise provided by the Minnesota Business
Corporation Act, Section 302A.223, as amended, when the shareholders have the
right to cumulate their votes.  A director named by the board of directors to
fill a vacancy may be removed from office at any time, with or without cause,
by the affirmative vote of the remaining directors if the shareholders have not
elected directors in the interim between the time of the appointment to fill
such vacancy and the time of the removal.  In the





                                      -5-

the authority of the board in the management of the business of the corporation
to the extent provided in the resolution.  A committee shall consist of one or
more persons, who need not be directors, appointed by affirmative vote of a
majority of the directors present.  Committees are subject to the direction and
control of, and vacancies in the membership thereof shall be filled by, the
board of directors.

           A majority of the members of the committee present at a meeting is a
quorum for the transaction of business, unless a larger or smaller proportion
or number is provided in a resolution approved by the affirmative vote of a
majority of the directors present.

           Section 3.12.Written Action.  Any action which might be taken at a
meeting of the board of directors, or any duly constituted committee thereof,
may be taken without a meeting if done in writing and signed by all of the
directors or committee members, unless the articles provide otherwise and the
action need not be approved by the shareholders.

           Section 3.13.Compensation.  Directors who are not salaried officers
of this corporation shall receive such fixed sum per meeting attended or such
fixed annual sum as shall be determined, from time to time, by resolution of
the board of directors.  The board of directors may, by resolution, provide
that all directors shall receive their expenses, if any, of attendance at
meetings of the board of directors or any committee thereof.  Nothing herein
contained shall be construed to preclude any director from serving this
corporation in any other capacity and receiving proper compensation therefor.

president, treasurer and such other officers as may be deemed advisable, each
of whom shall have the powers, rights, duties, responsibilities, and terms of

his or her office by the board of directors at any time, with or without cause.

           Section 4.06.Vice President.  Each vice president, if one or more is

consideration, including, without limitation, in consideration of cash or other
property, tangible or intangible, received or to be received by the corporation
under a written agreement, of services rendered or to be rendered to the
corporation under a written agreement, or of an amount transferred from surplus
to stated capital upon a share dividend.  At the time of approval of the

determination of the fair value to the corporation in monetary terms of any
consideration other than cash for which shares are to be issued.

the corporation may be authorized only by the shareholder named in the
certificate, or the shareholder's legal representative, or the shareholder's
duly authorized attorney-in-fact, and upon surrender of the certificate or the

and shall, if the board of directors so requires, give the corporation a bond
of indemnity in form, in an amount, and with one or more sureties satisfactory
to the board of directors, to indemnify the corporation against any claim which
may be made against it on account of the reissue of such certificate, whereupon
a new certificate may be issued in the same tenor and for the same number of
shares as the one alleged to have been lost, stolen or destroyed.

       Re:  ENStar Inc./Registration Statement on Form S-4

Ladies and Gentlemen:

           We have acted as counsel to ENStar Inc., a Minnesota corporation,
(the "Company"), in connection with a Registration Statement on Form S-4 (the
"Registration Statement") relating to the distribution by the Company of up to
3,357,400 shares of common stock of the Company, par value $.01 per share (the
"Common Stock").

           We have examined such documents and have reviewed such questions of
law as we have considered necessary and appropriate for the purposes of our
opinions set forth below.  In rendering our opinions set forth below, we have
assumed the authenticity of all documents submitted to us as originals, the
genuineness of all signatures and the conformity to authentic originals of all
documents submitted to us as copies.  We have also assumed the legal capacity
for all purposes relevant hereto of all natural persons and, with respect to
all parties to agreements or instruments relevant hereto other than the
Company, that such parties had the requisite power and authority (corporate or
otherwise) to execute, deliver and perform such agreements or instruments, that
such agreements or instruments have been duly authorized by all requisite
action (corporate or otherwise), executed and delivered by such parties and
that such agreements or instruments are the valid, binding and enforceable
obligations of such parties.  As to questions of fact material to our opinions,
we have relied upon certificates of officers of the Company and of public
officials.  We have also assumed that the Common Stock will be issued and sold
as described in the Registration Statement.

           Based on the foregoing, we are of the opinion that the shares of
Common Stock to be issued by the Company as described in the Registration
Statement have been duly authorized by all requisite corporate action and, upon





<PAGE>   2


issuance and delivery therefor as described in the Registration Statement, will
be validly issued, fully paid and nonassessable.

           Our opinions expressed above are limited to the laws of the State of
Minnesota.

           We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement, and to the reference to our firm under the heading
"Legal Matters" in the Prospectus constituting part of the Registration
Statement.

Dated:  March 20, 1996


                                                         Very truly yours,

           (w)    "Rule 16b-3" shall mean Rule 16b-3 promulgated by the
Securities and Exchange Commission under the Exchange Act or any successor rule
or regulation.

           (x)    "Shares" shall mean shares of Common Stock, $.01 par value,
of the Company or such other securities or property as may become subject to
Awards pursuant to an adjustment made under Section 4(c) of the Plan.

           (y)    "Stock Appreciation Right" shall mean any right granted under
Section 6(b) of the Plan.

Section 3.  Administration.

           (a)    Power and Authority of the Committee.  The Plan shall be

shall not be administered by the Committee but rather by the Board of Directors
subject to the provisions and restrictions of Section 7.  Subject to the

to Section 7 of the Plan, the Committee shall have full power and authority to:
(i) designate Participants; (ii) determine the type or types of Awards to be
granted to each Participant under the Plan; (iii) determine the number of
Shares to be covered by (or with respect to which payments, rights or other
matters are to be calculated in connection with) each

Award; (iv) determine the terms and conditions of any Award or Award Agreement;
(v) amend the terms and conditions of any Award or Award Agreement and
accelerate the exercisability of Options or the lapse of restrictions relating
to Restricted Stock, Restricted Stock Units or other Awards; (vi) determine
whether, to what extent and under what circumstances Awards may be exercised in
exchange for cash, Shares, promissory notes, other securities, other Awards or
other property, or canceled, forfeited or suspended; (vii) determine whether,
to what extent and under what circumstances cash, Shares, other securities,
other Awards, other property and other amounts payable with respect to an Award
under the Plan shall be deferred either automatically or at the election of the
holder thereof or the Committee; (viii) interpret and administer the Plan and
any instrument or agreement relating to, or Award made under, the Plan; (ix)
establish, amend, suspend or waive such rules and regulations and appoint such
agents as it shall deem appropriate for the proper administration of the Plan;
and (x) make any other determination and take any other action that the
Committee deems necessary or desirable for the administration of the Plan.
Unless otherwise expressly provided in the Plan, all designations,
determinations, interpretations and other decisions under or with respect to
the Plan or any Award shall be within the sole discretion of the Committee, may
be made at any time and shall be final, conclusive and binding upon any
Participant, any holder or beneficiary of any Award and any employee of the
Company or any Affiliate.

           (b)    Delegation.  The Committee may delegate its powers and duties
under the Plan to one or more officers of the Company or any Affiliate or a
committee of such officers, subject to such terms, conditions and limitations
as the Committee may establish in its sole discretion; provided, however, that
the Committee shall not delegate its powers and duties under the Plan (i) with
regard to officers or directors of the Company or any Affiliate who are subject
to Section 16 of the Exchange Act or (ii) in such a manner as would cause the
Plan not to comply with the requirements of Section 162(m) of the Code.

           (c)    Power and Authority of the Board of Directors.
Notwithstanding anything to the contrary contained herein, the Board of
Directors may, at any time and from time to time, without any further action of
the Committee, exercise the powers and duties of the Committee under the Plan
with regard to any Person who is not (i) an officer or director of the Company
or (ii) an Affiliate, in each case subject to Section 16 of the Exchange Act.

Section 4.  Shares Available for Awards.

           (a)    Shares Available.  Subject to adjustment as provided in
Section 4(c), the aggregate number of Shares which may be issued under all
Awards





                                      -4-
<PAGE>   5


under the Plan shall be 300,000.  Shares to be issued under the Plan may be
either Shares reacquired and held in the treasury or authorized but unissued
Shares.  If any Shares covered by an Award or to which an Award relates are not
purchased or are forfeited, or if an Award otherwise terminates without
delivery of any Shares, then the number of Shares counted against the aggregate
number of Shares available under the Plan with respect to such Award, to the
extent of any such forfeiture or termination, shall again be available for
granting Awards under the Plan.  Notwithstanding the foregoing, the number of
Shares available for granting Incentive Stock Options under the Plan shall not
exceed 300,000, subject to adjustment as provided in the Plan and Section 422
or 424 of the Code or any successor provision.

           (b)    Accounting for Awards.  For purposes of this Section 4, if an
Award entitles the holder thereof to receive or purchase Shares, the number of
Shares covered by such Award or to which such Award relates shall be counted on
the date of grant of such Award against the aggregate number of Shares
available for granting Awards under the Plan.

           (c)    Adjustments.  In the event that the Committee shall determine
that any dividend or other distribution (whether in the form of cash, Shares,
other securities or other property), recapitalization, stock split, reverse
stock split, reorganization, merger, consolidation, split-up, spin-off,
combination, repurchase or exchange of Shares or other securities of the
Company, issuance of warrants or other rights to purchase Shares or other
securities of the Company or other similar corporate transaction or event
affects the Shares such that an adjustment is determined by the Committee to be
appropriate in order to prevent dilution or enlargement of the benefits or
potential benefits intended to be made available under the Plan, then the
Committee shall, in such manner as it may deem equitable, adjust any or all of
(i) the number and type of Shares (or other securities or other property) which
thereafter may be made the subject of Awards, (ii) the number and type of
Shares (or other securities or other property) subject to outstanding Awards
and (iii) the purchase or exercise price with respect to any Award; provided,
however, that the number of Shares covered by any Award or to which such Award
relates shall always be a whole number.

           (d)    Award Limitations Under the Plan.  No Eligible Person may be
granted any Award or Awards under the Plan, the value of which Awards is based
solely on an increase in the value of the Shares after the date of grant of
such Awards, for more than 170,000 Shares in the aggregate in any calendar
year.  The foregoing annual limitation specifically includes the grant of any
Awards representing "qualified performance-based compensation" within the
meaning of Section 162(m) of the Code.

Section 5.  Eligibility.

           Any Eligible Person, including any Eligible Person who is an officer
or director (but not a Non-Employee Director) of the Company or any Affiliate,
shall be eligible to be designated a Participant.  In determining which
Eligible Persons shall receive an Award and the terms of any Award, the
Committee may take into account the nature of the services rendered by the
respective Eligible Persons, their present and potential contributions to the
success of the Company or such other factors as the Committee, in its
discretion, shall deem relevant.  Notwithstanding the foregoing, an Incentive
Stock Option may only be granted to full or part-time employees (which term as
used herein includes, without limitation, officers and directors who are also
employees), and an Incentive Stock Option shall not be granted to an employee
of an Affiliate unless such Affiliate is also a "subsidiary corporation" of the
Company within the meaning of Section 424(f) of the Code or any successor
provision.  Non-Employee Directors shall be eligible to receive Awards of
Non-Qualified Stock Options under the Plan only as provided in Section 7 of the
Plan.

Section 6.  Awards.

           (a)    Options.  The Committee is hereby authorized to grant Options
to Participants with the following terms and conditions and with such
additional terms and conditions not inconsistent with the provisions of the
Plan as the Committee shall determine:

           (i)    Exercise Price.  The purchase price per Share purchasable
       under an Option shall be determined by the Committee; provided, however,
       that such purchase price shall not be less than 100% of the Fair Market
       Value of a Share on the date of grant of such Option.

           (ii)   Option Term.  The term of each Option shall be fixed by the
       Committee.

           (iii)  Time and Method of Exercise.  The Committee shall determine
       the time or times at which an Option may be exercised in whole or in
       part and the method or methods by which, and the form or forms
       (including, without limitation, cash, Shares, promissory notes, other
       securities, other Awards or other property, or any combination thereof,
       having a Fair Market Value on the exercise date equal to the relevant
       exercise price) in which, payment of the exercise price with respect
       thereto may be made or deemed to have been made. 



                                                                           

                                      -6-
<PAGE>   7



           (iv)   Reload Options.  The Committee may grant Reload Options,
       separately or together with another Option, pursuant to which, subject
       to the terms and conditions established by the Committee and any
       applicable requirements of Rule 16b-3 or any other applicable law, the
       Participant would be granted a new Option when the payment of the
       exercise price of a previously granted option is made by the delivery of
       Shares owned by the Participant pursuant to Section 6(a)(iii) hereof or
       the relevant provisions of another plan of the Company, and/or when
       Shares are tendered or forfeited as payment of the amount to be withheld
       under applicable income tax laws in connection with the exercise of an
       Option, which new Option would be an Option to purchase the number of
       Shares not exceeding the sum of (A) the number of Shares so provided as
       consideration upon the exercise of the previously granted option to
       which such Reload Option relates and (B) the number of Shares, if any,
       tendered or withheld as payment of the amount to be withheld under
       applicable tax laws in connection with the exercise of the option to
       which such Reload Option relates pursuant to the relevant provisions of
       the plan or agreement relating to such option.  Reload Options may be
       granted with respect to Options previously granted under the Plan or any
       other stock option plan of the Company, and may be granted in connection
       with any Option granted under the Plan or any other stock option plan of
       the Company at the time of such grant.  Such Reload Options shall have a
       per share exercise price equal to the Fair Market Value as of the date
       of grant of the new Option.  Any Reload Option shall be subject to
       availability of sufficient Shares for grant under the Plan.  Shares
       surrendered as part or all of the exercise price of the Option to which
       it relates that have been owned by the optionee less than six months
       will not be counted for purposes of determining the number of Shares
       that may be purchased pursuant to a Reload Option.

           (b)    Stock Appreciation Rights.  The Committee is hereby
authorized to grant Stock Appreciation Rights to Participants subject to the
terms of the Plan and any applicable Award Agreement.  A Stock Appreciation
Right granted under the Plan shall confer on the holder thereof a right to
receive upon exercise thereof the excess of (i) the Fair Market Value of one
Share on the date of exercise (or, if the Committee shall so determine, at any
time during a specified period before or after the date of exercise) over (ii)
the grant price of the Stock Appreciation Right as specified by the Committee,
which price shall not be less than 100% of the Fair Market Value of one Share
on the date of grant of the Stock Appreciation Right.  Subject to the terms of
the Plan and any applicable Award Agreement, the grant price, term, methods of
exercise, dates of exercise, methods of settlement and any other terms and
conditions of any Stock Appreciation Right shall be as determined





                                      -7-
<PAGE>   8


by the Committee.  The Committee may impose such conditions or restrictions on
the exercise of any Stock Appreciation Right as it may deem appropriate.

           (c)    Restricted Stock and Restricted Stock Units.  The Committee
is hereby authorized to grant Awards of Restricted Stock and Restricted Stock
Units to Participants with the following terms and conditions and with such
additional terms and conditions not inconsistent with the provisions of the
Plan as the Committee shall determine:

            (i)   Restrictions.  Shares of Restricted Stock and Restricted
       Stock Units shall be subject to such restrictions as the Committee may
       impose (including, without limitation, any limitation on the right to
       vote a Share of Restricted Stock or the right to receive any dividend or
       other right or property with respect thereto), which restrictions may
       lapse separately or in combination at such time or times, in such
       installments or otherwise as the Committee may deem appropriate.

           (ii)   Stock Certificates.  Any Restricted Stock granted under the
       Plan shall be evidenced by issuance of a stock certificate or
       certificates, which certificate or certificates shall be held by the
       Company.  Such certificate or certificates shall be registered in the
       name of the Participant and shall bear an appropriate legend referring
       to the terms, conditions and restrictions applicable to such Restricted
       Stock.  In the case of Restricted Stock Units, no Shares shall be issued
       at the time such Awards are granted.

            (iii)Forfeiture; Delivery of Shares.  Except as otherwise
       determined by the Committee, upon termination of employment (as
       determined under criteria established by the Committee) during the
       applicable restriction period, all Shares of Restricted Stock and all
       Restricted Stock Units at such time subject to restriction shall be
       forfeited and reacquired by the Company; provided, however, that the
       Committee may, when it finds that a waiver would be in the best interest
       of the Company, waive in whole or in part any or all remaining
       restrictions with respect to Shares of Restricted Stock or Restricted
       Stock Units.  Any Share representing Restricted Stock that is no longer
       subject to restrictions shall be delivered to the holder thereof
       promptly after the applicable restrictions lapse or are waived.  Upon
       the lapse or waiver of restrictions and the restricted period relating
       to Restricted Stock Units evidencing the right to receive Shares, such
       Shares shall be issued and delivered to the holders of the Restricted
       Stock Units.

           (d)    Performance Awards.  The Committee is hereby authorized to
grant Performance Awards to Participants subject to the terms of the Plan and
any





                                      -8-

applicable Award Agreement.  A Performance Award granted under the Plan (i) may
be denominated or payable in cash, Shares (including, without limitation,
Restricted Stock and Restricted Stock Units), other securities, other Awards or
other property and (ii) shall confer on the holder thereof the right to receive
payments, in whole or in part, upon the achievement of such performance goals
during such performance periods as the Committee shall establish.  Subject to
the terms of the Plan and any applicable Award Agreement, the performance goals
to be achieved during any performance period, the length of any performance
period, the amount of any Performance Award granted, the amount of any payment
or transfer to be made pursuant to any Performance Award and any other terms
and conditions of any Performance Award shall be determined by the Committee.

           (e)    Dividend Equivalents.  The Committee is hereby authorized to
grant Dividend Equivalents to Participants under which such Participants shall
be entitled to receive payments (in cash, Shares, other securities, other
Awards or other property as determined in the discretion of the Committee)
equivalent to the amount of cash dividends paid by the Company to holders of
Shares with respect to a number of Shares determined by the Committee.  Subject
to the terms of the Plan and any applicable Award Agreement, such Dividend
Equivalents may have such terms and conditions as the Committee shall
determine.

           (f)    Other Stock-Based Awards.  The Committee is hereby authorized
to grant to Participants such other Awards that are denominated or payable in,
valued in whole or in part by reference to, or otherwise based on or related
to, Shares (including, without limitation, securities convertible into Shares),
as are deemed by the Committee to be consistent with the purpose of the Plan;
provided, however, that such grants must comply with Rule 16b-3 and applicable
law.  Subject to the terms of the Plan and any applicable Award Agreement, the
Committee shall determine the terms and conditions of such Awards.  Shares or
other securities delivered pursuant to a purchase right granted under this
Section 6(f) shall be purchased for such consideration, which may be paid by
such method or methods and in such form or forms (including, without
limitation, cash, Shares, promissory notes, other securities, other Awards or
other property or any combination thereof), as the Committee shall determine,
the value of which consideration, as established by the Committee, shall not be
less than 100% of the Fair Market Value of such Shares or other securities as
of the date such purchase right is granted.

           (g)    General.  Except as otherwise specified with respect to
Awards to Non-Employee Directors pursuant to Section 7 of the Plan:

              (i)No Cash Consideration for Awards.  Awards shall be granted for
       no cash consideration or for such minimal cash consideration as may be
       required by applicable law.

            (ii)  Awards May Be Granted Separately or Together.  Awards may, in
       the discretion of the Committee, be granted either alone or in addition
       to, in tandem with or in substitution for any other Award or any award
       granted under any plan of the Company or any Affiliate other than the
       Plan.  Awards granted in addition to or in tandem with other Awards or
       in addition to or in tandem with awards granted under any such other
       plan of the Company or any Affiliate may be granted either at the same
       time as or at a different time from the grant of such other Awards or
       awards.

           (iii)  Forms of Payment under Awards.  Subject to the terms of the
       Plan and of any applicable Award Agreement, payments or transfers to be
       made by the Company or an Affiliate upon the grant, exercise or payment
       of an Award may be made in such form or forms as the Committee shall
       determine (including, without limitation, cash, Shares, promissory
       notes, other securities, other Awards or other property or any
       combination thereof), and may be made in a single payment or transfer,
       in installments or on a deferred basis, in each case in accordance with
       rules and procedures established by the Committee.  Such rules and
       procedures may include, without limitation, provisions for the payment
       or crediting of reasonable interest on installment or deferred payments
       or the grant or crediting of Dividend Equivalents with respect to
       installment or deferred payments.

            (iv)  Limits on Transfer of Awards.  No Award and no right under
       any such Award shall be transferable by a Participant otherwise than by
       will or by the laws of descent and distribution; provided, however,
       that, if so determined by the Committee, a Participant may, in the
       manner established by the Committee, designate a beneficiary or
       beneficiaries to exercise the rights of the Participant and receive any
       property distributable with respect to any Award upon the death of the
       Participant.  Each Award or right under any Award shall be exercisable
       during the Participant's lifetime only by the Participant or, if
       permissible under applicable law, by the Participant's guardian or legal
       representative.  No Award or right under any such Award may be pledged,
       alienated, attached or otherwise encumbered, and any purported pledge,
       alienation, attachment or encumbrance thereof shall be void and
       unenforceable against the Company or any Affiliate.





                                     -10-
<PAGE>   11



            (v)   Term of Awards.  The term of each Award shall be for such
       period as may be determined by the Committee.

           (vi)   Restrictions; Securities Exchange Listing.  All certificates
       for Shares or other securities delivered under the Plan pursuant to any
       Award or the exercise thereof shall be subject to such stop transfer
       orders and other restrictions as the Committee may deem advisable under
       the Plan or the rules, regulations and other requirements of the
       Securities and Exchange Commission and any applicable federal or state
       securities laws, and the Committee may cause a legend or legends to be
       placed on any such certificates to make appropriate reference to such
       restrictions.  If the Shares or other securities are traded on a
       securities exchange, the Company shall not be required to deliver any
       Shares or other securities covered by an Award unless and until such
       Shares or other securities have been admitted for trading on such
       securities exchange.

Section 7.  Options to Non-Employee Directors.

           (a)    Eligibility.  If the Plan is approved by the shareholders of
the Company, Options shall be granted automatically under the plan to each
Non-Employee Director under the terms and conditions contained in this Section
7.  The authority of the Committee under this Section 7 shall be limited to
ministerial and non-discretionary matters.

           (b)    Annual Option Grants.  Each Non-Employee Director shall be
granted an Option to purchase 4,000 Shares upon his or her election or
appointment to the Board of Directors, and shall be granted an Option to
purchase 1,000 Shares on the date of the annual meeting of shareholders each
year, commencing with the 1997 Annual Meeting of Shareholders, if the
Non-Employee Director will remain in office immediately following such meeting.
The exercise price of each Option shall be equal to 100 percent of the Fair
Market Value per Share on the date of grant.  Such Options shall be
Non-Qualified Stock Options, shall become exercisable six months after the date
of grant, and shall terminate on the fifth anniversary of the date of grant,
unless previously exercised or terminated.  Such Options shall be subject to
the terms and conditions of Sections 6(a) and 10 of the Plan and to other
standard terms and conditions contained in the form of Non-Qualified Stock
Option Agreement used by the Company from time to time.  Such Options shall
also terminate three months following the date upon which the participant
ceases to be a director of the Company, except that:





                                     -11-
<PAGE>   12



           (i)    In the event that a Non-Employee Director who is granted an
       Option shall cease to be a director of the Company by reason of such
       director's willful and material misconduct, the Options shall terminate
       as of the date of such misconduct, and

           (ii)   If a Non-Employee Director who is granted an Option shall die
       while a director of the Company or within three months after he or she
       ceases to be a director of the Company for any reason other than willful
       and material misconduct, or if such director ceases to be a director of
       the Company by reason of his or her disability and he or she shall not
       have fully exercised the Option, the Option may be exercised at any time
       within 12 months after such director's death, or 12 months after
       cessation of directorship, in accordance with its terms by such
       director's legal representatives or administrators or by any person or
       persons to whom the Option has been transferred by will or the
       applicable laws of descent and distribution, but only to the extent of
       the full number of Shares such director was entitled to purchase under
       the Option on the date of death or cessation of directorship.

           (c)    Exercise of Non-Employee Director Options.  Non-Qualified
Stock Options granted to Non-Employee Directors may be exercised in whole or in
part from time to time by serving written notice of exercise on the Company at
its principal executive offices, to the attention of the Company's Secretary.
The notice shall state the number of Shares as to which the Option is being
exercised and be accompanied by payment of the purchase price.  A Non-Employee
Director may, at such Director's election, pay the purchase price by check
payable to the Company, by promissory note, in Shares, or in any combination
thereof having a Fair Market Value on the exercise date equal to the applicable
exercise price.  If payment or partial payment is made by promissory note, such
note shall be (i) full recourse, (ii) limited in principal amount to the
maximum amount permitted under applicable laws, rules and regulations, (iii)
bear interest at a rate not less than the minimum rate required to avoid the
imputation of income, original issue discount or a below-market-rate loan
pursuant to Sections 483, 1274 or 7872 of the Code or any successor provisions
thereto.

           (d)    Amendments to Section 7.  The provisions of this Section 7
may not be amended more often than once every six months other than to comply
with changes in the Code or the rules and regulations promulgated under the
Code.

           Except to the extent prohibited by applicable law and unless
otherwise expressly provided in an Award Agreement or in the Plan:

           (a)    Amendments to the Plan.  The Board of Directors of the
Company may amend, alter, suspend, discontinue or terminate the Plan; provided,
however, that, notwithstanding any other provision of the Plan or any Award
Agreement, without the approval of the shareholders of the Company, no such
amendment, alteration, suspension, discontinuation or termination shall be made
that, absent such approval:

           (i)    would cause Rule 16b-3 to become unavailable with respect to
       the Plan;

           (ii)   would violate the rules or regulations of the Nasdaq Stock
       Market, the National Association of Securities Dealers, Inc. or any
       securities exchange  that are applicable to the Company; or

           (iii)  would cause the Company to be unable, under the Code, to

are withheld or collected from such Participant.  In order to assist a
Participant in paying all or a portion of the federal and state taxes to be
withheld or collected upon exercise or receipt of (or the lapse of restrictions
relating to) an Award, the Committee, in its discretion and subject to such
additional terms and conditions as it may adopt, may permit the Participant to
satisfy such tax obligation by (i) electing to have the Company withhold a
portion of the Shares otherwise to be delivered upon exercise or receipt of (or
the lapse of restrictions relating to) such Award with a Fair Market Value
equal to the amount of such taxes or (ii) delivering to the Company Shares
other than Shares issuable upon exercise or receipt of (or the lapse of
restrictions relating to) such Award with a Fair Market Value equal to the
amount of such taxes.  The election, if any, must be made on or before the date
that the amount of tax to be withheld is determined.

           (b)    Tax Bonuses.  The Committee, in its discretion, shall have
the authority, at the time of grant of any Award under this Plan or at any time
thereafter, to approve cash bonuses to designated Participants (except to
Non-Employee Directors) to be paid upon their exercise or receipt of (or the
lapse of restrictions relating to) Awards in order to provide funds to pay all
or a portion of federal and state taxes due as a result of such exercise or
receipt (or the lapse of such restrictions).  The Committee shall have full
authority in its discretion to determine the amount of any such tax bonus.

Section 10.  General Provisions.

           (a)    No Rights to Awards.  No Eligible Person, Participant or
other Person shall have any claim to be granted any Award under the Plan, and
there is no obligation for uniformity of treatment of Eligible Persons,
Participants or holders or beneficiaries of Awards under the Plan.  The terms
and conditions of Awards need not be the same with respect to any Participant
or with respect to different Participants.

           (b)    Delegation.  The Committee may delegate to one or more
officers of the Company or any Affiliate or a committee of such officers the
authority, subject to such terms and limitations as the Committee shall
determine, to grant Awards to Eligible Persons who are not (i) officers or
directors of the Company or (ii) Affiliates, in each case subject to Section 16
of the Exchange Act.

           (c)    Award Agreements.  No Participant will have rights under an
Award granted to such Participant unless and until an Award Agreement shall
have been duly executed on behalf of the Company and, if requested by the
Company, signed by the Participant.





                                     -14-
<PAGE>   15



           (d)    No Limit on Other Compensation Arrangements.  Nothing
contained in the Plan shall prevent the Company or any Affiliate from adopting
or continuing in effect other or additional compensation arrangements, and such
arrangements may be either generally applicable or applicable only in specific
cases.

           (e)    No Right to Employment.  The grant of an Award shall not be
construed as giving a Participant or Non-Employee Director the right to be
retained in the employ of the Company or any Affiliate, nor will it affect in
any way the right of the Company or an Affiliate to terminate such employment
at any time, with or without cause.  In addition, the Company or an Affiliate
may at any time dismiss a Participant or Non-Employee Director from employment
free from any liability or any claim under the Plan, unless otherwise expressly
provided in the Plan or in any Award Agreement.

           (f)    Governing Law.  The validity, construction and effect of the
Plan or any Award, and any rules and regulations relating to the Plan or any
Award, shall be determined in accordance with the laws of the State of
Minnesota.

           (g)    Severability.  If any provision of the Plan or any Award is
or becomes or is deemed to be invalid, illegal or unenforceable in any
jurisdiction or would disqualify the Plan or any Award under any law deemed
applicable by the Committee (or, in the case of grants under Section 7 of the
Plan, the Board of Directors), such provision shall be construed or deemed
amended to conform to applicable laws, or if it cannot be so construed or
deemed amended without, in the determination of the Committee (or, in the case
of grants under Section 7 of the Plan, the Board of Directors), materially
altering the purpose or intent of the Plan or the Award, such provision shall
be stricken as to such jurisdiction or Award, and the remainder of the Plan or
any such Award shall remain in full force and effect.

           (h)    No Trust or Fund Created.  Neither the Plan nor any Award
shall create or be construed to create a trust or separate fund of any kind or
a fiduciary relationship between the Company or any Affiliate and a Participant
or any other Person.  To the extent that any Person acquires a right to receive
payments from the Company or any Affiliate pursuant to an Award, such right
shall be no greater than the right of any unsecured general creditor of the
Company or any Affiliate.

           (i)    No Fractional Shares.  No fractional Shares shall be issued
or delivered pursuant to the Plan or any Award, and the Committee shall
determine whether cash shall be paid in lieu of any fractional Shares or
whether such fractional Shares or any rights thereto shall be canceled,
terminated or otherwise eliminated.





                                     -15-

           (j)    Headings.  Headings are given to the Sections and subsections
of the Plan solely as a convenience to facilitate reference.  Such headings
shall not be deemed in any way material or relevant to the construction or
interpretation of the Plan or any provision thereof.

           (k)    Other Benefits.  No compensation or benefit awarded to or
realized by any Participant under the Plan shall be included for the purpose of
computing such Participant's compensation under any compensation-based
retirement, disability, or similar plan of the Company unless required by law
or otherwise provided by such other plan.

Section 11.  Section 16(b) Compliance.

           The Plan is intended to comply in all respects with Rule 16b-3 or
any successor provision, as in effect from time to time, and in all events the
Plan shall be construed in accordance with the requirements of Rule 16b-3.  If
any Plan provision does not comply with Rule 16b-3 as hereafter amended or
interpreted, the provision shall be deemed inoperative.  The Board of
Directors, in its absolute discretion, may bifurcate the Plan so as to
restrict, limit or condition the use of any provision of the Plan to
participants who are (i) officers or directors of the Company or (ii)
Affiliates, in each case subject to Section 16 of the Exchange Act, without so
restricting, limiting or conditioning the Plan with respect to other
participants.

Section 12.  Effective Date of the Plan.

           The Plan shall be effective as of the date of its approval by the
Board of Directors of the Company; provided, however, that if the Company's
shareholders do not approve the Plan, the Plan shall be null and void and all
Awards granted pursuant to the Plan shall be of no force or effect.

Section 13.  Term of the Plan.

           Awards shall only be granted under the Plan during a 10-year period
beginning on the effective date of the Plan.  However, unless otherwise
expressly provided in the Plan or in an applicable Award Agreement, any Award
theretofore granted may extend beyond the end of such 10-year period, and the
authority of the Committee provided for hereunder with respect to the Plan and
any Awards, and the authority of the Board of Directors of the Company to amend
the Plan, shall extend beyond the termination of the Plan.

                      NON-QUALIFIED STOCK OPTION AGREEMENT


       THIS AGREEMENT, made this ____________________ day of

corporation (the "Company") and ___________ ("Employee").

       WITNESSETH, THAT:

       WHEREAS, the Company pursuant to the ENStar 1996 Stock Incentive Plan

       NOW, THEREFORE, in consideration of the premises and of the mutual
covenants herein contained, the parties hereto hereby agree as follows:

            On or after each of                 of shares as to which
            the following dates                 option is exercisable

            ___________________                 _____________________

<PAGE>   18


           (b)    Notwithstanding the installment exercise provision set forth
in paragraph (a) above and subject to the other terms and conditions set forth
herein, this option may be exercised as to 100% of the Common Stock of the
Company for which this option was granted on the date of a "change of control"
as hereinafter defined.  A "change of control" shall mean any of the following:

                  (i)A sale of all or substantially all of the assets of the

           class) by any person (except a Permitted Shareholder as hereinafter
           defined) or group of persons acting in concert. A "Permitted
           Shareholder" means a holder, as of the date the Plan was adopted by
           the Company, of more than 20% of the Company Common Stock then
           outstanding.
                  (iii)A reorganization of the Company wherein the holders of
           Common Stock of the Company receive stock in another company, a
           merger of the Company with another company wherein there is a more
           than 50% change in the ownership of the Common Stock of the Company
           as a result of such merger, or any other transaction in which the
           Company (other than as the parent corporation) is consolidated for
           federal income tax purposes or is eligible to be consolidated for
           federal income tax purposes with another corporation.
                  (iv)In the event that the Common Stock of the Company is
           traded on an established securities market: a public announcement
           that any person has acquired or has the right to acquire beneficial
           ownership of more than 50% of the then outstanding Common Stock of
           the Company (for this purpose the terms "person" and "beneficial
           ownership" shall have the meanings provided in Section 13(d) of the
           Securities and Exchange Act of 1934 or related rules promulgated by
           the Securities and Exchange Commission) or the commencement of or
           public announcement of an intention to make a tender offer or
           exchange offer for more than 50% of the then outstanding Common
           Stock of the Company.
                  (v)The Board of Directors of the Company, in its sole and
           absolute discretion, determines that there has been a sufficient
           change in the share ownership of the Company to constitute a change
           of effective ownership or control of the Company.

       (c)        Notwithstanding the installment exercise provision set forth
in paragraph (a) above, this option will not be exercisable unless the
distribution of all of the outstanding common stock of the Company to the then
current shareholders of North Star Universal, Inc.  takes place within one year
of the date of this Agreement.

           (d)    During the lifetime of Employee, the option shall be
exercisable only by Employee and shall not be assignable or transferable by
Employee, other than by will or the laws of descent and distribution.

       3.  Effect of Termination of Employment

           (a)    In the event that Employee shall cease to be employed by the
Company or its subsidiaries, if any, for any reason other than Employee's
serious misconduct or Employee's death or disability (as such term is defined
in Section 3(c) hereof), Employee shall have the right to exercise the option
at any time within one (1) month after such termination of employment to the
extent of the full number of shares Employee was entitled to purchase under the
option on the date of termination, subject to the condition that no option
shall be exercisable after the expiration of the term of the option.

           (b)  In the event that Employee shall cease to be employed by the
Company or its subsidiaries, if any, by reason of Employee's serious misconduct
during the course of employment, including but not limited to wrongful
appropriation of the Company's funds, or in the event that Employee violates
the covenants set forth in Section 5 hereof, the option shall be terminated as
of the date of the misconduct.

           (c)  If Employee shall die while in the employ of the Company or a
subsidiary, if any, or within one (1) month after termination of employment for
any reason other than serious misconduct or if employment is terminated because
Employee has become disabled (within the meaning of Code Section 22(e)(3))
while in the employ of the Company or a subsidiary, if any, and Employee shall
not have fully exercised the option, such option may be exercised at any time
within twelve (12) months after Employee's death or date of termination of
employment for disability by Employee, personal representatives or
administrators, or guardians of Employee, as applicable, or by any person or
persons to whom the option is transferred by will or the applicable laws of
descent and distribution, to the extent of the full number of shares Employee
was entitled to purchase under the option on the date of death, termination of
employment, if earlier, or date of termination for such disability and subject
to the condition that no option shall be exercisable after the expiration of
the term of the option.

<PAGE>   20



       4.  Manner of Exercise

           (a)  The option can be exercised only by Employee or other proper
party by delivering within the option period written notice to the Company at
its principal office.  The notice shall state the number of shares as to which
the option is being exercised and be accompanied by payment in full of the
option price for all shares designated in the notice.

           (b)  Employee may pay the option price in cash, by check (bank
check, certified check or personal check), by money order, or with the approval
of the Company (i) by delivering to the Company for cancellation Common Stock
of the Company with a fair market value as of the date of exercise equal to the
option price or the portion thereof being paid by tendering such shares, (ii)
by delivering to the Company the full option price in a combination of cash and
Employee's full recourse liability promissory note with a principal amount not
to exceed eighty percent (80%) of the option price and a term not to exceed
five (5) years, which promissory note shall provide for interest on the unpaid
balance thereof which at all times is not less than the minimum rate required
to avoid the imputation of income, original issue discount or a below-market
rate loan pursuant to Sections 483, 1274 or 7872 of the Code or any successor
provisions thereto or (iii) by delivering to the Company a combination of cash,
Employee's promissory note and Common Stock of the Company with an aggregate
fair market value and a principal amount equal to the option price.  For these
purposes, the fair market value of the Common Stock as of any date shall be as
reasonably determined by the Company pursuant to the Plan.

       5.  Miscellaneous

           (a)    This option is issued pursuant to the ENStar 1996 Stock
Incentive Plan and is subject to its terms.  The terms of the Plan are
available for inspection during business hours at the principal offices of the
Company.

           (b)    This Agreement shall not confer on Employee any right with
respect to continuance of employment by the Company or any of its subsidiaries,
nor will it interfere in any way with the right of the Company to terminate
such employment at any time.  Employee shall have none of the rights of a
shareholder with respect to shares subject to this option until such shares
shall have been issued to Employee upon exercise of this option.





                                     -20-
<PAGE>   21



           (c)    The exercise of all or any parts of this option shall only be
effective at such time that the sale of Common Stock pursuant to such exercise
will not violate any state or federal securities or other laws.

           (d)    If there shall be any change in the Common Stock of the
Company through merger, consolidation, reorganization, recapitalization,
dividend in the form of stock (of whatever amount), stock split or other change
in the corporate structure of the Company, and all or any portion of the option
shall then be unexercised and not yet expired, then appropriate adjustments in
the outstanding option shall be made by the Company, in order to prevent
dilution or enlargement of option rights.  Such adjustments shall include,
where appropriate, changes in the number of shares of Common Stock and the
price per share subject to the outstanding option.

           (e)    The Company shall at all times during the term of the option
reserve and keep available such number of shares as will be sufficient to
satisfy the requirements of this Agreement.

           (f)    In order to provide the Company with the opportunity to claim
the benefit of any income tax deduction which may be available to it upon the
exercise of the option, and in order to comply with all applicable federal or
state income tax laws or regulations, the Company may take such action as it
deems appropriate to insure that, if necessary, all applicable federal or state
payroll, withholding, income or other taxes are withheld or collected from
Employee.  Employee may elect to satisfy his federal and state income tax
withholding obligations upon exercise of this option by (i) having the Company
withhold a portion of the shares of Common Stock otherwise to be delivered upon
exercise of such option having a fair market value equal to the amount of
federal and state income tax required to be withheld upon such exercise, in
accordance with the rules of the Committee, or (ii) delivering to the Company
shares of Common Stock other than the shares issuable upon exercise of such
option with a fair market value equal to such taxes, in accordance with the
rules of the Committee.

           (g)    Employee agrees to  disclose neither the contents nor any of
the terms and conditions of this option to any other person, and agrees that
such disclosure may result in both immediate termination of this option without
the right to exercise any part thereof and termination of employment with the
Company.

                                               Utilities

other place as may from time to time be designated by Landlord.

Base Rent during the Extension Option shall be at the then current Market Rent

landlord concessions, costs and allowances, such as (but without limitation)
tenant improvement allowance, free rent and leasing commissions.

In the event Landlord and Tenant are unable to agree to current Market Rent
within thirty (30) days of Tenant's exercise of its option, then the current
Market Rent shall be determined by arbitration.  Landlord and Tenant, within
fifteen (15) days thereafter, shall jointly appoint as arbitrator, a commercial
real estate appraiser with a minimum of ten (10) years experience in the
applicable market.  If Landlord and Tenant cannot agree on an acceptable
arbitrator, Landlord and Tenant shall choose, within an additional fifteen (15)
days thereafter, its own arbitrator who meets the qualifications described
above.  The arbitrators shall then jointly select, within an additional fifteen
(15) days, an arbitrator to serve as the arbitrator hereunder.  Within thirty
(30) days after appointment, the arbitrator shall determine the current Market
Rent.  The cost of the arbitrator(s) shall be borne equally by Landlord and
Tenant.

4.     OPERATING COSTS:

Tenant shall, for the entire Lease Term, except as provided in Section 3, pay
to Landlord as additional rent, without any set-off or deduction therefrom,

change in the laws, rules or regulations of any governmental authority having
jurisdiction, or for the purposes of reducing Operating Costs the extent of any
savings, which costs shall be amortized over the useful life of such
improvements or repairs, as reasonably estimated by Landlord.





                                     -2-

The amortization of capital costs to reduce Operating Costs shall not exceed
the resulting reduction in Operating Costs.

Not withstanding anything in Section 4 to the contrary, the following shall not
be deemed Operating Costs under this Lease:

(A)    Real estate brokerage commissions;
(B)    Legal fees incurred in leasing or in disputes with tenants;
(C)    Cost of construction allowances and similar lease inducement allowances
       provided to other tenants;
(D)    Interest or principal payments on any mortgage or deed of trust or any
       ground lease payments;
(E)    Any cost or expenditure for which Landlord is reimbursed from third
       parties, such as insurance proceeds or warranty claims;
(F)    Cost of any services furnished to other tenants but which Landlord does
       not furnish to Tenant;
(G)    Cost of repairs or maintenance caused or necessitated by the negligence
       of Landlord, its agents, contractors or employees;
(H)    Bad debt losses, rent losses and reserves for capital, rent losses and
       bad debts;
(I)    Subject to Tenant's obligations under Section 16, all costs of complying
       with laws, regulations, ordinances or governmental requirements in
       effect as of the date of this Lease relating to Hazardous Materials.

As soon as reasonably practicable prior to the commencement of each calendar
year during the Lease Term, Landlord shall furnish to Tenant an estimate of
Tenant's share of Operating Costs for the ensuing calendar year and Tenant
shall pay, as additional rent hereunder together with each installment of
monthly base rent, one-twelfth (1/12th) of its estimated annual share of such
Operating Costs.  Landlord's estimate for 1995 is $3.40 per square foot.  As
soon as reasonably practicable after the end of each calendar year during the
Lease Term, Landlord shall furnish to Tenant a reasonably detailed, itemized
statement of the actual Operating Costs for the previous calendar year,
including Tenant's share of such amount, and within thirty (30) days thereafter
Tenant shall pay to Landlord, or Landlord to Tenant, as the case may be, the
difference between such actual and estimated Operating Costs paid by Tenant.
Tenant's share of such Operating Costs for the years in which this Lease
commences and terminates shall be prorated based upon the dates of commencement
and termination of the Lease Term.

Landlord shall maintain all books and records relating to Operating Costs for a
particular year for a period of at least 120 days thereafter, and shall make
such books and records available to Tenant for inspection and copying at a
reasonably convenient location, upon 48 hours' advance notice.  Tenant shall
have the right, at Tenant's sole expense, at any time within 120 days after
Tenant's receipt of Landlord's statement of actual Operating Costs for any
calendar year, to have Landlord's books and records relating to such Operating
Costs audited by a certified public accountant reasonably acceptable to Tenant
and Landlord.  The results of any such audit shall be conclusive.  If the audit
determines that actual Operating Costs for any calendar year are different than
the amount shown on Landlord's statement, Landlord shall refund or Tenant shall
pay  the difference within 30 days after receiving the audit report.  Tenant
shall have the further right to have Landlord's books and records for the prior
three years audited by a certified public accountant and reasonably acceptable
to Tenant and Landlord, but only as to those items which have been shown to be
incorrect.  Landlord shall pay prior to delinquency all Operating Costs and all
payments due under any mortgage, deed of trust, ground lease or other
encumbrance against the Building or the Project.  Landlord shall cause all
assessments for local improvements to be paid in installments over the maximum
allowable period of time.

5.     ADDITIONAL TAXES:

Tenant shall pay as additional rent to Landlord, together with each installment
of monthly base rent, the amount of any gross receipts tax, sales tax or

payable, by Landlord, by reason of the receipt of the monthly base rent and
adjustments thereto.

6.     SECURITY DEPOSIT:  INTENTIONALLY DELETED

7.     UTILITIES:

Landlord shall provide mains and conduits to supply water, gas, electricity and
sanitary sewage to the Demised Premises.  Tenant shall pay, when due, all

electricity, gas, telephone and/or other utility services or energy source
furnished to the Demised Premises during the term of this Lease, or any renewal
or extension thereof, except as provided in Section 3..  If Landlord elects to
furnish any of the foregoing, the rate charged by Landlord for such utility
services or other services furnished or caused to be furnished by Landlord
shall not exceed the rate Tenant would be required to pay to a utility company
or service company furnishing any of the foregoing utilities or services.  The
charges thereof shall be deemed additional rent.

8.     CARE AND REPAIR OF DEMISED PREMISES:

Tenant shall, at all times throughout the term of this Lease, including
renewals and extensions, and at its sole expense, keep and maintain the Demised
Premises in a clean, safe, sanitary condition and in compliance with all
applicable laws, codes, ordinances, rules and regulations.  Tenant's
obligations hereunder shall include but not be limited to the maintenance,
repair and replacement, if necessary, of all lighting, HVAC and plumbing
fixtures and equipment, fixtures, motors and machinery (but only if located in
the Demised Premises or exclusively serving the Demised Premises), all interior
walls, partitions, doors and windows, including the regular painting thereof,
all exterior entrances, windows, doors and docks and the replacement of all
broken glass.  When used in this provision, the term "repairs" shall include
replacements or renewals when necessary, and all such repairs made by the
Tenant shall be equal in quality and class to the original work.  The Tenant
shall keep and maintain all interior portions of the Demised Premises in a
clean and orderly condition.

Tenant shall not be obligated for maintenance, repair and replacement to the
extent coverable by insurance Landlord is obligated to maintain.

Landlord shall cause all HVAC and plumbing fixtures and equipment, fixtures,
motors and machinery to be in good operating condition as of the commencement
of this Lease.  Subject to Tenant's obligations under Section 9.L. of this
Lease, Landlord warrants the good operation of all HVAC and plumbing fixtures
and of equipment, fixtures, motors and machinery for a period of one year from
the commencement of this Lease.

If Tenant fails, refuses or neglects to maintain or repair the Demised Premises
as required in this Lease after reasonable notice shall have been given Tenant,
Landlord may make such repairs without liability to Tenant for any loss or
damage that may accrue to Tenant's merchandise, fixtures or other property or
to Tenant's business by reason thereof, and upon completion thereof, Tenant
shall pay to Landlord all costs plus 15% for overhead incurred by Landlord in
making such repairs upon presentation





                                     -4-

to Tenant of bill therefor.  Landlord shall keep the foundation, exterior walls
(except plate glass or glass or other breakable materials used in structural
portions) and roof in good repair, and if necessary or required by proper
governmental authority, made modifications or replacements thereof, except that
Landlord shall not be required to make any such repairs, modifications or
replacements which are not coverable by insurance and which become necessary or
desirable by reason of the negligence of Tenant, its agents, servants or
employees.

The Landlord shall maintain, repair and manage in good condition all common
areas of the Project, including grounds and parking areas consistent with
prevailing standards for similar projects in the Minneapolis - St. Paul
metropolitan area.  The cost of said maintenance shall be prorated in
accordance with Section 4 of this Lease.  All such maintenance which is
provided by Landlord shall be provided as reasonably necessary for the
comfortable use and occupancy of the Demised Premises, upon the condition that
the Landlord shall not be liable for damages for failure to do so due to causes
beyond its control.

9.     COVENANTS OF TENANT:

Tenant agrees that it shall:
A.     Observe such reasonable and uniform rules and regulations as from time
       to time may be put in effect by Landlord for the general safety, comfort
       and convenience of Landlord, occupants and tenants of the Building.
B.     Give Landlord access to the Demised Premises at all reasonable times,
       upon reasonable prior notice, without change or diminution of rent, to
       enable Landlord to examine the same and to make such repairs, additions
       and alterations as Landlord may deem advisable, and during the ninety
       (90) days prior to the expiration of the term, to exhibit the Demised
       Premises to prospective tenants and to place upon the door or in the
       windows of the Demised Premises any usual or ordinary "For Lease" signs.
       Landlord shall not exercise its rights under this Section in any manner
       which unreasonably interferes with or disturbs Tenant's use or enjoyment
       of the Demised Premises.
C.     Replace all glass broken by Tenant with glass of the same quality as
       that broken, save only glass broken by fire or other casualty coverable
       by standard all risk insurance, and commit no waste on the Demised
       Premises.
D.     Pay for all electric lamps, starters and ballasts used in the Demised
       Premises.
E.     Upon the termination of this Lease in any manner whatsoever, remove
       Tenant's goods and effects and those of any other person claiming under
       Tenant, and quit and deliver up the Demised Premises to Landlord
       peaceably and quietly in as good order and condition as the same are now
       in or hereafter may be put in by Landlord or Tenant, reasonable use and
       wear thereof, casualty, condemnation and repairs which are Landlord's
       obligation excepted.  Goods and effects not removed by Tenant at the
       termination of this Lease, however terminated, shall be considered
       abandoned and Landlord may dispose of the same as it deems expedient.
F.     Except for an assignment or subletting to an affiliate or a wholly owned
       subsidiary of Tenant, the Tenant may not assign this Lease, or sublet
       all or any part of said Demised Premises, without the Landlord's prior
       written consent, which consent shall not be unreasonably withheld,
       conditioned or delayed.  The Landlord reserves the right, should the
       Tenant request such assignment or subletting of the entire Demised
       Premises, to release the Tenant from the terms and conditions of this
       Lease and the Landlord shall have thirty (30) days to make such
       determination.  Should the Landlord exercise this right, the Lease shall
       terminate.  Until such termination, the Tenant will, however, remain
       liable for the performance of all the terms and conditions hereof.





                                     -5-

G.     Not place signs on or about the exterior of the Demised Premises without
       first obtaining Landlord's written consent thereto.
H.     Not overload, damage or deface the Demised Premises or do any act which
       may make void or voidable any insurance on the Demised Premises or the
       Building, or which may render an increased or extra premium payable for
       insurance.
I.     Not place any additional locks on any of Tenant's doors without the
       written consent of the Landlord.
J.     Not make any alterations or additions to the Demised Premises costing in
       excess of $10,000.00 when aggregated over any period of twelve
       consecutive months or which affect the safety or utility of the Demised
       Premises without obtaining the prior written approval of the Landlord
       thereto, and all alterations, additions or improvements (including
       carpeting or other floor covering which has been glued or otherwise
       affixed to the floor) which may be made by either of the parties hereto
       upon the Demised Premises, except movable office furniture and
       equipment, shall be the property of Landlord, and shall remain upon and
       be surrendered with the Demised Premises, as a part thereof, at the
       termination of this Lease.
K.     Keep the Demised Premises and the Project free from any mechanics',
       materialmen's, contractors' or other liens arising from, or any claims
       for damages growing out of, any work performed, materials furnished or
       obligations incurred by or on behalf of Tenant.  Provided, however, that
       Tenant shall have the right to contest any such lien, in which event
       such lien shall not be considered a default under this Lease until the
       existence of the lien has been finally adjudicated and all appeal
       periods have expired.  Tenant shall indemnify and hold harmless Lessor
       from and against any such lien, or claim or action thereon, reimburse
       Lessor promptly upon demand therefor by Lessor for costs of suit and
       reasonable attorneys' fees incurred by Lessor in connection with any
       such lien, claim or action, and, upon written request of Lessor, provide
       Lessor with a bond in an amount and under circumstances necessary to
       obtain a release of the Demised Premises or the Project from such lien.
L.     Cause to be performed by a competent service company, preventative
       maintenance of all HVAC units and warehouse unit heaters serving the
       Demised Premises, as recommended by the equipment manufacturer.

Tenant's obligations under this paragraph numbered 9 to do or not to do a
specified act shall extend to and include Tenant's obligations to see to it
that Tenant's employees, agents and invitees shall do or shall not do such
acts, as the case may be.

10.    PARKING AND DRIVES:

The Tenant, its employees, and invitees shall have the non-exclusive right,
without charge except as provided in Section 4, to use the common driveways and
parking lots along with the other tenants and customers of the building.  The
use of such driveways and parking facilities are subject  to such reasonable
rules and regulations as the Landlord may impose.  The Tenant further agrees
not to use, or permit the use by its employees, the parking areas for the
overnight storage of automobiles or other vehicles without the written
permission of Landlord.

Landlord shall provide, on an as-is, non-exclusive basis (subject to Landlord's
repair and maintenance obligation) and without charge of any kind (other than
Operating Costs as provided in Section 4), a minimum of 3.8 parking stalls per
1,000 square feet of leasable area in the Building.  Landlord shall designate
with appropriate signage five parking spaces for visitor parking.  Landlord
shall not take any action to reduce the number of parking stalls located on the
land and serving the Building as of the date of this Lease.





                                     -6-
<PAGE>   7



11.    CASUALTY LOSS:

In case of damage to the Demised Premises or the Building by fire or other
casualty, Tenant shall give immediate notice to Landlord, who shall thereupon
cause the damage to be repaired with reasonable speed, at the expense of the
Landlord, subject to delays which may arise by reason of adjustment of loss
under insurance policies and for delays beyond the reasonable control of
Landlord, and to the extent that the Demised Premises are rendered
untenantable, the rent shall proportionately abate.  In the event the damage
shall be so extensive that the cost of repair would exceed thirty percent (30%)
of the value of the Building, and Landlord shall decide not to repair or
rebuild, this Lease shall, at the option of Landlord, be terminated as of the
date of such damage by written notice from the Landlord to the Tenant given
within 60 days of such damage, and the rent shall be adjusted to the date of
such damage and Tenant shall thereupon promptly vacate the Demised Premises.

If Landlord fails to complete the repair and restoration of the Building and
Demised Premises within 180 days after the date of any such damage or
destruction, then Tenant may terminate this Lease by giving written notice
thereof to Landlord at any time after such 180 day period and prior to
completion of such repairs and restoration.

12.    CONDEMNATION:

If the entire Demised Premises is taken by eminent domain or transferred under
threat of such taking, this Lease shall automatically terminate as of the date
of taking.  If a portion of the Demised Premises are taken by eminent domain,
either party shall have the right to terminate this Lease as of the date of
taking by giving written notice thereof to the other within ninety (90) days
after such date of taking.  If neither party elects to terminate this Lease,
Landlord shall, at its expense, restore the Demised Premises, exclusive of any
improvements or other changes made therein by Tenant, to as near the condition
which existed immediately prior to the date of taking as reasonably possible,
and to the extent that the Demised Premises are rendered untenantable, the rent
shall proportionately abate.  All damages awarded for a taking under the power
of eminent domain shall belong to and be the exclusive property of Landlord,
whether such damages be awarded as compensation for diminution in value of the
leasehold estate hereby created or to the fee of the Demised Premises;
provided, however, that Landlord shall not be entitled to any separate award
made to Tenant for relocation expenses and the value and cost of removal of its
personal property and fixtures.

13.    DELAY IN POSSESSION:

If the Demised Premises shall, on the scheduled date of commencement of the
Lease Term, not be ready for occupancy by the Tenant due to the possession or
occupancy thereof by any person not lawfully entitled thereto, or because
construction has not yet been completed, or by reason of any building
operations, repair or remodeling to be done by Landlord, Landlord shall use due
diligence to complete such construction, building operations, repair or
remodeling and to deliver possession of the Demised Premises to Tenant.  except
as hereinafter provided, the Landlord, using such due diligence, shall not in
any way be liable for failure to obtain possession of the Demised Premises for
Tenant or to timely complete such construction, building operations, repair or
remodeling, but the rental and other charges payable by Tenant hereunder shall
be abated until the Demised Premises shall, on Landlord's part, be ready for
occupancy by Tenant, and the commencement and expiration dates and all other
dates herein shall be extended by the period of delay, this Lease remaining in
all other respects in full force and effect.





                                     -7-
<PAGE>   8



If construction of the Leasehold Improvements to be completed by Landlord shall
not have commenced by June 14, 1995, Tenant may terminate this Lease by
telephone message to Landlord or Landlord's agent, delivered no later than 5:00
PM, June 14, 1995.

14.    MUTUAL RELEASE/WAIVER OF SUBROGATION:

Landlord and Tenant each hereby release the other from any and all liability or
responsibility for any direct or consequential loss, injury or damage to the
Demised Premises, or its contents, caused by fire or any other casualty, during
the term of this Lease, even if such fire or casualty may have been caused by
the negligence (but not the willful act) of the other party or one for whom
such party may be responsible.  Inasmuch as the above mutual waivers will
preclude the assignment of any aforesaid claim by way of subrogation (or
otherwise) to an insurance company (or any other person), each party hereto
agrees if required by said policies to give to each insurance company which has
issued to it all risk and other property insurance, written notice of the terms
of said mutual waivers, and to have said insurance policies properly endorsed,
if necessary, to prevent the invalidation of said insurance coverage by reason
of said waivers.

Tenant shall not carry any stock of goods or do anything in or about said
Demised Premises which will increase standard insurance rates on said Demised
Premises or the Building in which the same are located.  If Landlord shall
consent to such use, Tenant agrees to pay as additional rental any increase in
premiums for all risk insurance resulting from the business carried on in the
Demised Premises by Tenant.  Tenant shall, at its own expense, comply with the
requirements of insurance underwriters and insurance rating bureaus and
governmental authorities having jurisdiction.

The Tenant shall maintain in full force and effect during the term hereof, a
policy of commercial general liability insurance under which Landlord is named
additional insured.  The minimum limits of liability of such insurance shall be
$2,000,000.00 combined single limit as to bodily injury and property damage.
Tenant agrees to deliver a duplicate copy of said policy, or a certificate of
insurance evidencing such coverage, to Landlord.  Such policy shall contain a
provision requiring thirty (30) days written notice to Landlord before
cancellation of the policy can be effected.

Landlord shall maintain, at all times during the Lease Term and any extension
thereof, (i) an "all risk" or equivalent form property insurance policy,
insuring the Building and the Leasehold Improvements for their full replacement
cost, without deduction for depreciation, and with a deductible amount not to
exceed $25,000; (ii) boiler and machinery insurance in an amount equal to the
full replacement cost of the Building and Leasehold Improvements, with a
deductible amount not to exceed $25,000.00.

Upon the request of the Tenant, Landlord shall provide evidence of insurance.

15.    INDEMNIFICATION AND HOLD HARMLESS:

Tenant does hereby agree to defend, indemnify and hold Landlord harmless from
and against any and all liability for any injury to or death of any person or
persons or any damage to property in any way arising out of or in connection
with the condition, use or occupancy of the Premises, or in any way arising out
of any activities in or about the Premises, of Tenant, its assignees or
subtenants or of the respective agents, employees, licensees, contractors or
invitees of Tenant or its assignees or subtenants, and from all costs, expenses
and liabilities (including, but not limited to, court costs and reasonable
attorney's fees) incurred by Landlord in connection therewith.





                                     -8-
<PAGE>   9



Tenant covenants and agrees that Landlord shall not be liable to Tenant for any
injury to or death of any person or persons or for damage to any property of
Tenant, or any person claiming through Tenant, arising out of any accident or
occurrence in or about the Premises, including, but not limited to, injury,
death or damage caused by the Premises being out of repair or caused by any
defect in or failure of equipment, pipes or wiring, or caused by broken glass,
or caused by the backing up of drains, or caused by gas, water, steam,
electricity, or oil leaking, escaping or flowing into the Premises, or caused
by fire or smoke.

Tenant agrees to report in writing to Landlord any defective condition in or
about the Premises known to Tenant, and further agrees to attempt to contact
Landlord by telephone immediately in such instance.

16.    HAZARDOUS SUBSTANCES:

Tenant covenants and agrees that Tenant shall not (either with or without
negligence) cause or permit the escape, disposal or release of any biologically
or chemically active or other hazardous substances or materials in violation of
applicable laws.  Tenant shall not allow the storage or use of such substances
or materials in any manner not sanctioned by law or by the standards prevailing
in the industry for the storage and use of such substances or materials, nor
allow to be brought into the Project any such materials or substances except to
use in the ordinary course of Tenant's business, and then only after written
notice is given to Landlord of the identity of such substances or materials.
Without limitation, hazardous substances and materials shall include those
described in the Comprehensive Environmental Response Compensation and
Liability Act of 1980, as amended, 42 U.S.C. Section 9601 et. seq., and
applicable state or local laws and the regulations adopted under these acts.
If any lender or governmental agency shall ever require testing to ascertain
whether or not there has been any release of hazardous materials, and such
testing determines that Tenant has caused the release, then the reasonable
costs thereof shall be reimbursed by Tenant to Landlord upon demand as
additional charges if such requirement applies to the Demised Premises.  In
addition, Tenant shall execute affidavits, representations and the like from
time to time at Landlord's request concerning Tenant's best knowledge and
belief regarding Tenant's use of hazardous substances or materials on the
Demised Premises.  In all events, Tenant shall indemnify Landlord as referenced
in Section 15, from all actual investigation and remediation costs reasonably
incurred by Landlord as a result of any release of hazardous materials caused
by Tenant on the Demised Premises or elsewhere if caused by Tenant or persons
acting under Tenant in violation of this Lease or applicable law.  The within
covenants shall survive the expiration or earlier termination of the Lease
term.

Tenant has received a copy of the Phase I Environmental Survey Site Assessment
prepared by W.W. Engineering and Science dated April 15, 1994.

To the best of Landlord's knowledge, there are no other environmental issues
relating to the Property.

17.    DEFAULT:

Tenant hereby agrees that in case Tenant shall default in making its payments
hereunder  or any of them or in performing any of the other agreements, terms
and conditions of this Lease, then, in any such event, Landlord, in addition to
all other rights and remedies available to Landlord by law or by other
provisions hereof, may after ten days written notice (with respect to monetary
defaults) and 30 days written notice (with respect to all other defaults), with
due process, re-enter immediately into the Demised Premises and remove  all
persons and property therefrom, and, at Landlord's option, annul and





                                     -9-
<PAGE>   10


cancel this Lease as to all future rights of Tenant and Tenant hereby expressly
waives the service of any notice in writing of intention to re-enter as
aforesaid.  If a nonmonetary default occurs which cannot reasonably be cured
within 30 days after notice from Landlord, then Landlord shall not exercise any
of its remedies as a result of such default  for a period of 90 days after such
non-monetary default as long as Tenant has commenced and is diligently pursuing
reasonable efforts to cure such default.  Tenant further agrees that in case of
any such termination Tenant  will indemnify the Landlord against all loss of
rents and other damage which Landlord incurs by reason of such termination,
including, but not being limited to, costs of restoring and repairing the
Demised Premises and putting the same in rentable condition, costs of renting
the Demised Premises to another tenant, loss of diminution of rents and other
damage which Landlord may incur by reason of such termination, and all
reasonable attorney's fees and expenses incurred in enforcing any of the terms
of the Lease.  Neither acceptance of rent by Landlord, with or without
knowledge of breach, nor failure of Landlord to take action on account of any
breach hereof or to enforce its rights hereunder shall be deemed a waiver of
any breach, and absent written notice or consent, said breach shall be a
continuing one.

18.    NOTICES:

All bills, statements, notices of communications which Landlord may desire or
be required to give to Tenant shall be deemed sufficiently given or rendered if
in writing and sent by registered or certified mail addressed to Tenant at the
Demised Premises and the time of rendition thereof of the giving of such notice
or communication shall be deemed to be the time when the same is delivered to
Tenant or deposited in the mail as herein provided.  Any notice by Tenant to
Landlord must be served by registered or certified mail addressed to Landlord
at the address where the last previous rental hereunder was payable, or in case
of subsequent change upon notice given, to the latest address furnished and the
time of rendition thereof of the giving of such notice or communication shall
be deemed to be the time when the same is delivered to Tenant or deposited in
the mail as herein provided.

19.    HOLDING OVER:

Should Tenant continue to occupy the Demised Premises after expiration of the
Lease Term or any renewal or renewals thereof, or after a forfeiture incurred,
such tenancy shall be from month to month and in no event from year to year or
for any longer term.  Landlord shall charge Tenant a holdover rent equal to
150% of Base Rent and Operating Costs last in effect hereunder.

20.    SUBORDINATION:

Subject to the non-disturbance rights set forth below, the rights of Tenant
shall be and are subject and subordinate at all times to the lien of any first
mortgage now or hereafter in force against the project, and Tenant shall
execute such further instruments subordinating this Lease to the lien of any
such first mortgage as shall be requested by Landlord, provided, however, the
holder of such first mortgage shall agree not to disturb Tenant's rights under
this Lease so long as Tenant is not in default hereunder.

Landlord shall obtain and deliver to Tenant, within 30 days after the date of
this Lease, a written agreement, in form and substance reasonably acceptable to
Tenant, from each mortgagee, ground lessor, beneficiary of a deed of trust, or
other party holding a lien on any part of the Project (collectively, the
"Holder"), in which the Holder agrees to recognize Tenant's rights under this
Lease and not to disturb Tenant's possession of the Demised Premises in the
event of any foreclosure or termination of Landlord's interest in the Demised
Premises or the Project.

21.    ESTOPPEL CERTIFICATE:

Tenant shall at any time and from time to time, upon not less than ten (10)
days prior written notice from Landlord, execute, acknowledge and deliver to
Landlord and any other parties designated by Landlord, a statement in writing
certifying (a) that this Lease is in full force and effect and is unmodified
(or, if modified, stating the nature of such modification), (b) the date to
which the rental and other charges payable hereunder have been paid in advance,
if any, and (c) that there are, to Tenant's knowledge, no uncured defaults on
the part of Landlord hereunder (or specifying such defaults if any are
claimed).  Any such statement may be furnished to and relied upon by any
prospective purchaser, Tenant or encumbrancer of all or any portion of the
Project.

22.    SERVICE CHARGE:

Tenant agrees to pay a service charge equal to one percent (1%) per month or
any portion thereof of any payment of monthly base rent or additional charge
payable by Tenant hereunder which is not paid within ten (10) days from the
date due, or of $50.00 per month or portion thereof, whichever is greater.

23.    BINDING EFFECT:

The word "Tenant", wherever used in this Lease, shall be construed to mean
tenants in all cases where there is more than one tenant, and the necessary
grammatical changes required to make the provisions hereof apply to
corporations, partnerships or individuals, men or women, shall in all cases be
assumed as though in each case fully expressed.  Each provision hereof shall
extend to and shall, as the case may require, bind and inure to the benefit of
Landlord and Tenant and their respective heirs, legal representatives,
successors and assigns, provided that this Lease shall not inure to the benefit
of any heir, legal representative, transferee or successor of Tenant except
upon the express written consent or election of Landlord.  The Landlord may
assign its right, title, and interest in this Lease, and such assignment shall
thence terminate all the assigning Landlord's obligations thereafter arising,
provided the assignee assumes such obligation in writing.

24.    LEASEHOLD IMPROVEMENT COSTS:

Landlord shall provide all space planning, construction, mechanical and
engineering drawings at its sole cost and expense.

Landlord will complete, at its expense, on or before July 15, 1995, all of the
improvements ("Leasehold Improvements") to the Demised Premises in accordance
with the plans and specifications identified in Exhibit _____ attached hereto
(the "Plans").

Changes to the Plans as requested by Tenant from time to time shall be
performed by Landlord, provided that any such changes shall be subject to
Landlord's prior approval, which approval shall not be withheld except where
the changes (i) violate any applicable laws or require an amendment or variance
to the applicable zoning ordinance or a special permit, (ii) in Landlord's
reasonable judgment, materially and adversely effect the exterior appearance of
the Buildings or the exterior appearance of other areas of the Demised
Premises, or (iii) would result in a violation of the provisions of this Lease,
(iv) or would result in a delay in the Commencement of the Term.  Landlord
shall, before proceeding with any change, submit to Tenant in writing within
five (5) business days after Tenant notifies Landlord of the change or request
therefor, an estimate of the additional cost, if any, of the change and





                                     -11-
<PAGE>   12


the additional period of time, if any, the change will add to the scheduled
date for completion of the Leasehold Improvements.  If Tenant fails to approve
such statement within five (5) business days following receipt thereof, the
same shall be deemed disapproved and Landlord shall not proceed with the
change.  If Tenant approves said statement within said period, Landlord shall
cause the approved change to be made.  Landlord shall promptly proceed with the
change as soon as reasonably practical after Tenant's written (i) approval of
the foregoing statement by Landlord and (ii) agreement to pay the net
additional costs of such change as estimated by Landlord, determined on the
basis of actual out-of-pocket costs for labor and materials, plus contractor's
and subcontractor's fees not to exceed a total of six percent (6%) of labor and
materials costs, after deducting any savings resulting from such change or any
prior changes approved by Tenant.  Any such amount shall be paid in cash within
30 days after the later of (i) Tenant's receipt of Landlord's itemized invoice
showing a breakdown of such additional cost and including such backup
documentation as may be reasonably requested by Tenant, or (ii) completion of
the Leasehold Improvements.

Upon substantial completion of the Leasehold Improvements, Landlord, Tenant and
Landlord's architect shall execute a written instrument (the "Punch List")
identifying those minor details of construction, decoration and mechanical
adjustments remaining to be completed by Landlord which do not materially
interfere with Tenant's use and occupation of the Demised Premises ("Punch List
Items").  Full execution and delivery of the Punch List shall constitute
Tenant's acceptance of the Demised Premises; provided, however, that such
acceptance shall be subject to the completion of such Punch List Items within a
period of sixty (60) days after the commencement date.  In addition to the
foregoing Punch List Items, Tenant shall have the right to include as a part of
said Punch List Items any other uncompleted items (the "Additional Punch List
Items") which Tenant discovers while occupying the Demised Premises during the
aforesaid sixty (60) day period, which Additional Punch List Items shall be
completed or corrected by Landlord as soon as reasonably possible.  Tenant's
acceptance of the Demised Premises shall not relieve Landlord of liability for
any defect or deficiency therein.

If within one year after the Commencement of this Lease any of the work is
found to be defective due to faulty workmanship or materials, and if within
such period Tenant notifies Landlord thereof in writing, then Landlord shall
correct the same at its expense within a reasonable time after receipt of such
notice.  Tenant shall notify Landlord promptly after discovery of the
condition.

25.    BROKERAGE FEES:

Landlord shall pay a brokerage fee ("Brokerage Fees") of $3.00 per square foot
to The Shelard Group.  The Shelard Group and Northco Real Estate shall divide
this fee under the terms of a separate agreement.  The Landlord and Tenant each
warrant that there are no other claims for Broker's Commissions or finder fees
in connection with this Lease by any party with whom it has dealt.  Tenant and
Landlord hereby indemnifies and mutually holds each other harmless from and
against all loss, cost, damage or expense including, but not limited to,
attorney's fees and court costs incurred as a result of a claim made by a real
estate broker or agent through the Tenant or Landlord, respectively.

26.    SIGNAGE:

Upon the City of Eden Prairie's approval, Tenant shall have the option to
install signage on the Building.  Said signage shall be in accordance with all
applicable sign criteria for the Building, and subject to Landlord's consent,
which shall not be unreasonably withheld.

27.    AMERICANS WITH DISABILITIES ACT:

The parties agree that the liabilities and obligations of Landlord and Tenant
under that certain federal statute commonly known as the Americans With
Disabilities Act (42 U.S.C. 12101 et seq.) as well as the regulations and
accessibility guidelines promulgated thereunder as each of the foregoing is
supplemented or amended from time to time (collectively, the "ADA") shall be
apportioned as follows:

A.     Landlord represents and warrants to Tenant that all common areas of the
       Building and the Project, including, but not limited to, exterior and
       interior horizontal and vertical routes of ingress and egress,
       off-street parking, and all rules and regulations applicable to the
       Demised Premises, the Building or the Project, now comply, or shall be
       promptly made to comply by Landlord, at Landlord's sole cost and
       expense, with the ADA.  Landlord shall also cause its manager of the
       Building and the Project (the "Manager") to comply with the ADA in its
       operation of the Building and the Project.  Notwithstanding any
       provision of this Lease to the contrary, Landlord shall not be permitted
       to pass through to Tenant, as an Operating Cost or otherwise, any cost
       incurred by Landlord or the Manager in causing the Building or the
       Project to comply with the ADA, as presently published, as aforesaid.

B.     From and after the commencement date of the Lease, and subject to
       performance by Landlord of its obligations under subparagraph A
       immediately above, Tenant covenants and agrees to conduct its operations
       within the Demised Premises in compliance with the ADA.  In the event
       that Tenant elects to undertake any alterations to, for or within the
       Demised Premises, including initial build-out work if such work,
       pursuant to other terms of this Lease, is the responsibility of Tenant
       to perform, then Tenant agrees to cause such alterations to be performed
       in compliance with the ADA.  In the event that Tenant shall be required
       to make any alterations within the Demised Premises in order to make the
       Demised Premises comply with the ADA and such required alterations are
       not required because of Landlord's failure to perform its obligations
       under subparagraph A immediately above, then, to the extent any other
       term of this Lease requires the Tenant to obtain the Landlord's consent
       to make such alterations, Landlord hereby agrees to provide such consent
       to Tenant.

28.    QUIET ENJOYMENT:

Landlord hereby covenants that if Tenant pays the rent and other charges and
performs the covenants and agreements contained herein, Tenant shall peaceably
and quietly hold and enjoy the Demised Premises during the Lease Term and
extensions thereof.

29.    LANDLORD'S WARRANTIES:

Landlord warrants to Tenant that (i) the Demised Premises are zoned to permit
the use thereof for the purposes contemplated by this Lease without requiring a
variance or special or conditional use permit, and such use will not violate
any applicable Private Restrictions, and (ii) Landlord has good and marketable
fee simple absolute title to the Project, free from any liens and encumbrances
which would interfere with Tenant's use and enjoyment of the Demised Premises
and common areas for the purposes provided in this Lease.

       4.  Operating Costs.  Tenant shall, for the entire Lease Term, pay to
Lessor as additional rent, without any set-off or deduction therefrom, a pro
rata share of all costs which Lessor may incur in owning, maintaining, and
operating the Project.  Said costs are referred to herein as "Operating Costs"
and are hereby defined to installments of special assessments payable with
respect to the Project, maintenance, repair, replacement and care of all
heating, lighting, plumbing and air conditioning fixtures, equipment and

Operating Costs, which costs shall be amortized over the useful life of such
improvements or repairs, as reasonably estimated by Lessor, and which in the

costs, shall not exceed the actual amount of operating cost reduction.

of each calendar year during the Lease Term, Lessor shall furnish to Tenant a
certified statement of the actual Operating Costs for the previous calendar
year, including Tenant's share of such amount, and within thirty (30) days
thereafter Tenant shall pay to Lessor, or Lessor to Tenant as the case may be,

Tenant.  Tenant's share of such excess Operating Costs for the years in which
this Lease commences and terminates shall be prorated based upon the dates of
commencement and termination of the Lease Term.  Also see Rider, paragraph 3.

       5.  Additional Taxes.  Tenant shall pay as additional rent to Lessor,

energy source furnished to the Demised Premises during the term of this Lease,
or any renewal or extension thereof.  If Lessor elects to furnish any of the
foregoing utility services or other services furnished or caused to be

utilities or services.  The charges thereof shall be deemed additional rent in
accordance with Section 4.

       8.  Care and Repair of Demised Premises.  Tenant shall, at all times
throughout the terms of this Lease, including renewals and extensions, and at
its sole expense, keep and maintain the Demised Premises in a clean, safe,
sanitary and first class condition and in compliance with all applicable laws,
codes, ordinances, rules and regulations.  Tenant's obligations hereunder shall

necessary, of all lighting and plumbing fixtures and equipment, fixtures,
motors and machinery, all interior walls, partitions, doors and windows,
including the regular painting thereof, all exterior entrances, windows, doors
and docks and the replacement of all broken glass.  When used in this
provision, the term "repairs" shall include replacements or renewals when
necessary, and all such repairs made by the Tenant shall be equal in quality
and class to the original work.  The Tenant shall keep and maintain all
portions of the Demised Premises and the sidewalk and areas adjoining the same
in a clean and orderly condition, free of accumulation of dirt, rubbish, snow
and ice.  *Refer to Rider, paragraph 13.

Premises as required in this Lease after notice shall have been given Tenant,
Lessor may make such repairs without liability to Tenant for any loss or damage
that may accrue to Tenant's merchandise, fixtures or other property or to
Tenant's business by reason thereof, and upon completion thereof, Tenant shall
pay to Lessor all costs plus 15% for overhead incurred by Lessor in making such
repairs upon presentation to Tenant of invoices therefor provided said repairs
are reasonably visible to Lessor, and unless repairs are of an urgent or
emergency nature, Lessor shall provide Tenant with written notice of Tenant's
failure to make repairs, and Tenant shall have 30 days to cure the deficiency.
Lessor shall keep the foundation, exterior walls (except plate glass or glass
or other breakable materials used in structural portion) and roof in good
repair, and if necessary or required by proper governmental authority, make
modifications or replacements thereof, except that Lessor shall not be required
to make any such repairs, modifications or replacements which become necessary
or desirable by reason of the negligence of Tenant, its agents, servants or





                                     -3-
<PAGE>   4


employees, or by reason of anyone illegally entering or upon the premises,
repairs, modifications or replacements are covered and collectible under the
insurance policies required to be maintained by LESSOR under the terms and
conditions of this Lease, unless the cost of said repairs, modifications or
replacements are covered and collectible under the insurance policies required
to be maintained by LESSOR under the terms and conditions of this Lease.

       The Lessor shall manage all outside maintenance of the Demised Premises,
including grounds and parking areas.  The cost of said maintenance shall be
prorated in accordance with Section 4 of this Lease.  All such maintenance
which is provided by Lessor shall be provided as reasonably necessary for the
comfortable use and occupancy of Demised Premises during business hours, except
Saturdays, Sundays, and holidays, upon the condition that the Lessor shall not
be liable for damages for failure to do so due to causes beyond its control.

       9.  Covenants of Tenant.  Tenant agrees that it shall:
           A.     Observe such rules and regulations as from time to time may
                  be put in effect by Lessor for the general safety, comfort
                  and convenience of Lessor, occupants and tenants of said
                  Building, and which rules and regulations shall be consistent
                  with the terms and conditions of the Lease and uniformly
                  enforced.

           B.     Give Lessor access to the Demised Premises at all reasonable
                  times, without change or diminution of rent, to enable Lessor
                  to examine the same and to make such repairs, additions and
                  alterations as Lessor may deem advisable, and during the
                  ninety (90) days prior to the expiration of the term, to
                  exhibit the Premises to prospective tenants and to place upon
                  the door or in the windows of the Demised Premises any usual
                  or ordinary "For Lease" signs.  Lessor will use reasonable
                  efforts to provide Tenant with 24 hours notice before
                  entering the space.

           C.     Keep the Demised Premises in good order and condition and
                  replace all glass broken by Tenant with glass of the same
                  quality as that broken, save only glass broken by fire and
                  extended coverage risks, and commit no waste on the Demised
                  Premised.

           D.     Pay for all electric lamps, starters and ballasts used in the
                  Demised Premises.

           E.     Upon the termination of this Lease in any manner whatsoever,
                  remove Tenant's goods and effects and those of any other
                  person 





                                     -4-
<PAGE>   5


                  claiming under Tenant, and quit and deliver up the DEmised
                  Premises to Lessor peaceably and quietly in as good order 
                  and condition as the same are now in or hereafter may be 
                  put in by Lessor or Tenant, reasonably use and wear
                  thereof and repairs which are Lessor's obligation excepted. 
                  Goods and effects not removed by Tenant at the termination of
                  this Lease, however, terminated, shall be considered
                  abandoned and Lessor may dispose of the same as it deems
                  expedient.

           F.     Except for an assignment or subletting to an affiliate or a
                  wholly owned subsidiary of Tenant or the parent corporation,
                  the Tenant may not assign this Lease, or sublet all or any
                  part of said Demised Premises, without the Lessor's prior
                  written consent, which consent shall not be unreasonably
                  withheld.  The Lessor reserves the right, should the Tenant
                  request such assignment or subletting, to release the Tenant
                  from the terms and provisions of this Lease and the Lessor
                  shall have thirty (30) days to make such determination.
                  Should the Lessor exercise this right, the Lease shall
                  terminate.  Until termination hereof, the Tenant will,
                  however, still remain liable for the performance of all the
                  terms and conditions hereof.

           G.     Not place signs on or about the Demised Premises without
                  first obtaining Lessor's written consent thereto.

           H.     Not overload, damage or deface the Demised Premises or do any
                  act which may make void or voidable any insurance on the
                  Demised Premises or the building, or which may render an
                  increased or extra premium payable for insurance.

           I.     Not place any additional locks on any of Tenant's doors
                  without the written consent of the Lessor.  The Lessor shall
                  have the right to keep pass keys to the Demised Premises.

           J.     Not make any alterations or additions to the Demised Premises
                  without obtaining the prior written approval of the Lessor
                  thereto, except cosmetic or decorative changes, which shall
                  not require Lessor's consent provided that the changes are
                  consistent or of better quality than existing improvements,
                  and all alterations, additions or improvements (including
                  carpeting or other floor covering which has been glued or
                  otherwise affixed to the floor) which may be made by either
                  of the parties hereto





                                     -5-

                  upon the Demised Premises, except movable office furniture
                  and equipment shall be the property of Lessor, and shall
                  remain upon and be surrendered with the Demised Premises, as
                  a part thereof, at the termination of this Lease.

           K.     Cause to be performed by a competent service company,
                  preventative maintenance of all roof top HVAC units and
                  warehouse unit heaters serving the Demised Premises, as
                  recommended by the equipment manufacturer.

       Tenant's obligations under this paragraph numbered 9 to do or not to do
a specified act shall extend to and include Tenant's obligations to see to it
that Tenant's employees, agents and invitees shall do or shall not do such
acts, as the case may be.

       10.        Parking and Drives.  The Tenant, its employees, and invitees
shall have the non-exclusive right to use the common driveways and parking lots
along with the other tenants and customers of the building.  The use of such
driveways and parking facilities are subject to such reasonable rules and
regulations as the Lessor may impose.  The Tenant further agrees not to use, or
permit the use by its employees, the parking areas for the overnight storage of
automobiles or other vehicles without the written permission of Lessor.

       11.        Casualty Loss.  In case of damage to the Demised Premises or
the Building by fire or other casualty, Tenant shall give immediate notice to
Lessor, who shall thereupon cause the damage to be repaired with reasonable
speed, at the expense of the Lessor, subject to delays which may arise by
reason of adjustment of loss under insurance policies and for delays beyond the
reasonable control of Lessor, and to the extent that the Demised Premises are
rendered untenantable, the rent shall proportionately abate.  Lessor shall
commence repair and restoration promptly and with due diligence.  If the
premises cannot be restored in 180 days, force majeure excepted, Tenant may
terminate the lease by providing Lessor with 30 days written notice.  In the
event the damage shall be so extensive that the Lessor shall decide not to
repair or rebuild, this Lease shall, at the option of Lessor, be terminated as
of the date of such damage by written notice from the Lessor to the Tenant, and
the rent shall be adjusted to the date of such damage and Tenant shall
thereupon promptly vacate the Demised Premises.  In the event the damage shall
be so extensive such that more than fifty percent (50%) of the Building has 
been destroyed, this Lease shall, at the option of either Lessor or Tenant, be
terminated as of the date of such damage by written notice from either party to 
the other, and the rent shall be adjusted to the date of such damage and Tenant 
shall thereupon promptly vacate 



                                     -6-

the Demised Premises.  Lessor agrees to insure the building at replacement cost 
and such policy shall contain a waiver of subrogation against Tenant.

       12.        Condemnation.  If the entire Demised Premises are taken by
eminent domain, this Lease shall automatically terminate as of the date of
taking.  If a portion of the Demised Premises are taken by eminent domain,
Lessor shall have the right to terminate this Lease as of the date of taking by
giving written notice thereof to Tenant within ninety (90) days after such date
of taking.  If Lessor does not elect to terminate this Lease, it shall, at its
expense, restore the Demised Premises, exclusive of any improvements or other
changes made therein by Tenant, to as near the condition which existed
immediately prior to the date of taking as reasonably possible, and to the
extent that the Demised Premises are rendered untenantable, the rent shall
proportionately abate.  All damages awarded for a taking under the power of
eminent domain shall belong to and be the exclusive property of Lessor, whether
such damages be awarded as compensation for diminution in value of the
leasehold estate hereby created or to the fee of the Demised Premises;
provided, however, that Lessor shall not be entitled to any separate award made
to Tenant for the value and cost of removal of its personal property and
fixtures.

       13.        Delay in Possession.  If the Demised Premises shall on the
scheduled date of commencement of the Lease Term not be ready for occupancy by
the Tenant due to the possession or occupancy thereof by any person not
lawfully entitled thereto, or because construction has not yet been completed,
or by reason of any building operations, repair or remodeling to be done by
Lessor, Lessor shall use due diligence to complete such construction, building
operations, repair or remodeling and to deliver possession of the Demised
Premises to Tenant.  The Lessor, using such due diligence, shall not in any way
be liable for failure to obtain possession of the Demised Premises for Tenant
or to timely complete such construction, building operations, repair or
remodeling, but the rental and other charges payable by Tenant hereunder shall
be abated until the Demised Premises shall, on Lessor's part, be ready for the
occupancy of Tenant, this Lease remaining in all other respects in full force
and effect and the Lease Term not thereby extended.  Refer also to the Rider,
paragraph 1.

       14.        Mutual Release/Waiver of Subrogation.  Lessor and Tenant each
hereby release the other from any and all liability or responsibility for any
direct or consequential loss, injury or damage to the Demised Premises, or its
contents, caused by fire or any other casualty, during the term of this Lease,
even if such fire or any other casualty, during the term of this Lease, even if
such fire or other casualty may have been caused by the negligence (but not the
willful act) of the other party or one for whom such party may be responsible.
Inasmuch as the above mutual waivers will preclude the assignment of any
aforesaid claim by way of





                                     -7-
<PAGE>   8


subrogation (or otherwise) to an insurance company (or any other person), each
party hereto agrees if required by said policies to give to each insurance
company which has issued to it fire and other property insurance, written
notice of the terms of said mutual waivers, and to have said insurance policies
properly endorsed, if necessary, to prevent the invalidation of said insurance
coverage by reason of said waivers.

       Tenant shall not carry any stock of goods or do anything in or about
said Leased Premises which will increase insurance rates on said Leased
Premises or the Building in which the same are located.  If Lessor shall
consent to such use, Tenant agrees to pay as additional rental any increase in
premiums for insurance against loss by fire or extended coverage risks
resulting from the business carried on in the Leased Premises by Tenant.
Tenant shall, at its own expense, comply with the requirements of insurance
underwriters and insurance rating bureaus and governmental authorities having
jurisdiction.

       The Tenant shall maintain in full force and effect during the term
hereof, a policy of public liability insurance under which Lessor and Tenant
are named insured.  The minimum limits of liability of such insurance shall be
$1,000,000.00 combined single limit as to bodily injury and property damage.
Tenant agrees to deliver a duplicate copy of said policy, or a certificate of
insurance evidencing such coverage, to Lessor.  Such policy shall contain a
provision requiring ten (10) days written notice to Lessor before cancellation
of the policy can be effected.

       15.        Default.  Tenant hereby agrees that in case Tenant shall
default in making its payments hereunder or any of them or in performing any of
the other agreements, terms and conditions of this Lease, then, in any such
event, Lessor, in addition to all other rights and remedies available to Lessor
by law or by other provisions hereof, may after ten days written notice, with
due process, re-enter immediately into the Demised Premises and remove all
persons and property therefrom, and, at Lessor's option, annul and cancel this
Lease as to all future rights of Tenant and Tenant hereby expressly waives the
service of any notice in writing of intention to re-enter as aforesaid.  Tenant
further agrees that in case of any such termination Tenant will indemnify the
Lessor against all loss of rents and other damage which Lessor incurs by reason
of such termination, including, but not being limited to, costs of restoring
and repairing the Demised Premises and putting the same in rentable condition,
costs of renting the Demised Premises to another tenant, loss or diminution of
rents and other damage which Lessor may incur by reason of such termination,
and all reasonable attorney's fees and expenses incurred in enforcing any of
the terms of the Lease.  Neither acceptance of rent by Lessor, with or without
knowledge of breach, nor failure of Lessor to take action on account of any





                                     -8-
<PAGE>   9


breach hereof or to enforce its right hereunder shall be deemed a waiver of any
breach, and absent written notice or consent, said breach shall be a continuing
one.

                        Refer also to Rider, paragraph 8

       16.        Notices.  All bills, statements, notices of communications
which Lessor may desire or be required to give to Tenant shall be deemed
sufficiently given or rendered if in writing and either delivered to Tenant
personally or sent by registered or certified mail addressed to Tenant at the
Demised Premises and the time of rendition thereof of such notice or
communication shall be deemed to be the time when the same is delivered to
Tenant or deposited in the mail as herein provided.  Any notice by Tenant to
Lessor must be served by registered or certified mail addressed to Lessor at
the address where the last previous rental hereunder was payable, or in case of
subsequent change upon notice given, to the latest address furnished.

       17.        Holding Over.  Should Tenant continue to occupy the Demised
Premises after expiration of the Lease term or any renewal or renewals thereof,
or after a forfeiture incurred, such tenancy shall be from month to month and
in no event from year to year or for any longer term.

       18.        Subordination.  The rights of Tenant shall be and are subject
and subordinate at all times to the lien of any first mortgage now or hereafter
in force against the project, provided such Mortgagee agrees not to disturb
Tenant's possession if Tenant attorns to such Mortgagee, and Tenant shall
execute such further instruments subordinating this Lease to the lien of any
such first mortgage as shall be required by Lessor.
                       Refer also to Rider, Paragraph 14

       19.        Estoppel Certificate.  Tenant shall at any time and from time
to time, upon not less than ten (10) days' prior written notice from Lessor,
execute, acknowledge and deliver to Lessor and any other parties designated by
Lessor, a statement in writing certifying (a) that this Lease is in full force
and effect and is unmodified (or, if modified, stating the nature of such
modifications), (b) the date to which the rental and other charges payable
hereunder have been paid in advance, if any, and (c) that there are, to
Tenant's knowledge, no uncured defaults on the part of Lessor hereunder (or
specifying such defaults if any are claimed).  Any such statement may be
furnished to and relied upon by an prospective purchaser, tenant or
encumbrancer of all or any portion of the Project.

       20.        Service Charge.  Tenant agrees to pay a service charge equal
to one percent (1.0%) per month or any portion thereof of any payment of
monthly base





                                     -9-
<PAGE>   10


rent or additional charge payable by Tenant hereunder which is not paid within
fifteen (15) days from the date due, or of $25.00 per month or portion thereof,
whichever is greater.

       21.        Binding Effect.  The word "Tenant", wherever used in this
Lease, shall be construed to mean tenants in all cases where there is more than
one tenant, and the necessary grammatical changes required to make the
provisions hereof apply to corporations, partnerships or individuals, men or
women, shall in all cases by assumed as though in each case fully expressed.
Each provision hereof shall extend to and shall, as the case may require, bind
and inure to the benefit of Lessor and Tenant and their respective heirs, legal
representatives, successors and assigns, provided that this Lease shall not
inure to the benefit of any heir, legal representative, transferee or successor
of Tenant except upon the express written consent or election of Lessor.  The
Lessor may assign its right, title, and interest in this Lease, and such
assignment shall thence terminate all the Lessor's obligations.

                            RIDER TO LEASE AGREEMENT


       THIS RIDER to Lease Agreement is a Rider attached to and forming a part
of that certain Lease Agreement dated February 21st, 1989, by and between
RYAN/FLYING CLOUD ASSOCIATES LIMITED PARTNERSHIP, as Lessor ("LESSOR"), and
AMERICABLE INCORPORATED, a Minnesota Corporation, as Tenant ("TENANT"), as the
same shall modify, amend, supplement or alter the terms and provisions of said
Lease Agreement and by these presents shall be incorporated therein by
reference and form a part thereof for all purposes.

       In consideration of the premises, and for other good and valuable
consideration, the receipt and sufficiency of which is hereby acknowledged, the
Parties hereto further mutually agree as follows:

1.     Commencement Date

       Provided that the Lease is executed by February 21, 1989, and plans are
       approved by Tenant by February 24, Lessor shall use its best efforts to
       complete construction and to deliver the premises by the commencement
       date of May 15, 1989.  The lease shall not start before May 15, 1989.
       In event that delivery of the premises is delayed beyond May 15, 1989
       but not beyond June 29, 1989, (force majeure excepted) there will be no
       penalty to Lessor.

       In the event that occupancy is delayed, the day a Certificate of
       Occupancy is received shall be the lease commencement date.  From the
       lease commencement date, the lease shall continue through the 73rd month
       following said date, and terminate on the last day of the 73rd month.

       The rent schedule shall start on the commencement date and Tenant shall
       receive no less than five full months of base rent abatement.

       Provided the Lease is executed by February 21, 1989, and plans are
       approved by Tenant by February 24, and if construction is not completed
       and a Certificate of Occupancy not received by June 29, 1989, (force
       majeure excepted) there will be a penalty to Lessor.  For each one day
       the commencement date is delayed beyond June 29, 1989, Tenant shall
       receive a credit equivalent to 1.5 times the combined rent and operating
       costs for each day of delay.  For each working day that lease execution
       or plan approval by Tenant is delayed beyond February 21, 1989 and
       February 24, 1989, respectively, the penalty start date shall be moved
       back one working day.

2.     Net Rental Rate and Monthly Base Rent

       The net rental rate and monthly base rent shall be established as
       follows:

       A.  Months 1-5

           *      Net rental rate - $0.00 per square foot
           *      Monthly base rent - abated

       B.  Months 6-18

           *      Net rental rate - $3.50 per square foot
           *      Monthly base rent - $10,039.00

       C.  Months 19-60

           *      Net rental rate - $4.58 per square foot
           *      Monthly base rent - $13,136.00

       D.  Months 61-73 1/2

           *      Net rental rate - $5.65 per square foot
           *      Monthly base rent - $16,205.00

       E.  Monthly base rents are subject to change based on final measurement
           of square footage.

3.     Operating Costs

       Operating costs for the first eighteen (18) months of the lease term
       shall be fixed at $2.50 per square foot.  Thereafter, the operating
       costs shall be determined in accordance with the terms and conditions
       set forth in paragraph 4 of the Lease Agreement.

       For the purpose of this Lease, Tenant's "prorata share" of Operating
       Costs shall be that percentage obtained by dividing the rentable area of
       the Demised Premises (initially estimated to be 34,818 square feet) by
       the total rentable area of the Building (estimated to be 77,076 square
       feet), which calculation, if such measurements do not change, will
       result in a prorata share of forty-five percent (45%).





                                     -13-
<PAGE>   14



       Operating costs shall specifically exclude:

       A.  Leasing commissions, attorneys' fees, costs and other expenses
           incurred in connection with the negotiations or disputes with
           tenants, other occupants or prospective tenants of the building or
           due to any breach or violation by Landlord or any tenant of any
           lease;

       B.  costs incurred in renovating or otherwise improving, decorating or
           redecorating for tenants or other occupants in the building;

       C.  repairs or other work occasioned by fire, windstorm or other
           casualty, the costs of which are reimbursed to Landlord by insurers
           (or would have been reimbursed assuming that Lessor is carrying the
           insurance coverage required by the lease) or by governmental
           authorities in eminent domain proceedings;

       D.  costs of correcting defects in the design or construction of the
           building including latent defects;

       E.  costs which under generally accepted accounting principles,
           consistently applied are capitalized; except as delineated in
           paragraph 4 of the lease and in this paragraph of the Rider.

       F.  costs of Landlord's general corporate overhead and general
           administrative expenses;

       G.  costs incurred in advertising or other marketing or promotional
           activities designed primarily to market space in the building;

       H.  penalties or interest charged for failure to pay real estate taxes
           before they become delinquent or failure to promptly comply with
           laws related to the building.

       The fee charged by Lessor for management of the building shall not
       exceed 4% of gross rents.

       Provided Tenant has paid in full all rent and additional rent billed to
       date, Tenant shall have a period of up to ninety (90) days after receipt
       of Landlord's certified statement of expenses in which to challenge any
       item, request invoices or other backup or to elect to perform an audit.
       If the audit shows an overstatement by five percent (5%) or more, the
       cost of the audit should be paid for by Landlord, otherwise, the cost
       should be paid Tenant.  In any event,





                                     -14-
<PAGE>   15


       any difference in costs revealed by the audit should be promptly
       adjusted between Landlord and Tenant.

       Regarding amortization of capital costs as permitted under the terms and
       conditions of this Lease, such costs shall be amortized over the useful
       life of the applicable improvements or repairs as reasonably estimated
       by Lessor and, if requested by Tenant, as confirmed by an independent
       engineer or similar professional, whose fees shall be paid for by
       Tenant.

4.     Interior Tenant Improvements

       Lessor, at its expense, agrees to construct the space in accordance with
       the plans and specifications drawn by Walsh Bishop Associates dated
       December 20, 1988 and revised January 25, 1989 (attached here as Exhibit
       A), and in accordance with the specification outline attached here as
       Exhibit B.  Lessor also agrees to pay all reasonable space planning
       charges incurred through the services of Walsh Bishop through January
       24, 1989.  The total cost for the above described improvements plus
       space planning charges is estimated at $242,177.  It is mutually agreed
       that Lessor and Tenant will use their best efforts to reduce this cost
       to $230,000.

       Any subsequent changes to the plans and specifications at Tenant's which
       result in total interior construction and space planning costs exceeding
       the estimate $242,177, shall be at Tenant's expense.

       Ryan Construction Company of Minnesota shall act as the general
       contractor.  Tenant shall have the right to suggest appropriate union
       subcontractors when the plans let out to bid.  Lessor at its sole
       discretion reserves the right to select subcontractors based on bid
       price, references and proven subcontractor reliability.

       Lessor shall obtain from the general contractor, for the benefit of
       Tenant, a one (1) year warranty against defects in construction of the
       improvements to the Demised Premises, including specifically, any
       defects in materials and workmanship.

       In addition, Tenant shall deliver to Lessor at the time of occupancy any
       punch-list items which will be promptly completed by Lessor or Lessor's
       contractor.  Lessor shall also be responsible for any latent defects in
       construction.

5.     Exterior Tenant Improvements





                                     -15-
<PAGE>   16



       Lessor, at its expense, agrees to construct all modifications to the
       exterior structure of the building as shown on the plans drawn by Walsh
       Bishop Associates and dated January 24, 1989, and attached here as
       Exhibit A.  Lessor shall use its best efforts to complete exterior
       improvements simultaneously with interior improvements and subject to
       the same deadline and penalty provisions outlined in paragraph 1 of this
       Rider.

6.     Landlord's Consent

       In all cases where Landlord's consent is required, such consent shall 
       not be unreasonably withheld.

7.     Parking

       A.  Lessor agrees to add 20 parking stalls (thereby increasing the total
           number of parking stalls to 159) by summer of 1989 as weather
           permits.  Failure to complete the addition of these parking stalls
           is not to be deemed a condition that shall delay the commencement
           date of the Lease.  Lessor hereby advises Tenant that Lessor is
           endeavoring to add stalls up to a total of 162 stalls, subject to
           City approval of plans and specifications already submitted to the
           City of Eden Prairie.

       B.  Lessor shall provide Tenant with six reserved parking stalls in the
           front of the building.  Tenant recognizes that Lessor cannot
           effectively enforce the proper use of these stalls.

8.     Default by Tenant

       Tenant shall have the following grace periods, from receipt of written
       notice by Lessor, in which to cure the default:

       A.  Non-payment of rent, additional rent, or other sums which may be due
           pursuant to the terms of the lease:  15 days.

       B.  Other defaults:  30 days, unless the nature of the default is such
           that it cannot be reasonably cured within 30 days, in which case
           Tenant will not be deemed in default as long as Tenant promptly
           commences to cure the default and diligently proceeds to complete
           the cure.

9.     Option to Renew





                                     -16-
<PAGE>   17



       Tenant shall have two (2) options to renew the Lease Term for successive
       three (3) year periods.  Each option shall be exercised, if at all, by
       Tenant providing Lessor with at least six (6) months written notice
       thereof.  Base Rent shall be adjusted on first day of each three (3)
       year option period to the then-prevailing market rate for lease
       transactions of comparable size and type and for similar properties in
       the same general geographic area, giving due regard to concessions then
       being offered to tenants, such as free rent and improvement allowances.
       However, in no event shall the base rent including said concessions and
       allowances be less than $5.65 net (on an effective basis after
       subtracting concessions and allowances) per square foot per year.

10.    Memorandum of Lease

       Lessor agrees to deliver to Tenant within 30 days following lease
       execution a Memorandum of Lease in a form acceptable to Lessor which
       Tenant may place of record in the office of the Hennepin County
       Recorder.

11.    Utilities

       Lessor warrants that electric and gas service to the Demised Premises
       are submetered and that Tenant's share of electric and gas utilities
       service shall be determined based on monthly readings of these meters,
       which readings shall be conducted by Lessor and/or Tenant.

       Lessor warrants that water and sewer service to the Demised Premises is
       not separately metered and Tenant shall pay its pro rata share of water
       and sewer expense.  The definition of "pro rata share" has been
       delineated in the Rider, paragraph 3.

12.    Guaranty of Lease

       This Lease is contingent upon the execution of the Guaranty of Lease
       (attached herein as Exhibit C) by North Star Universal, Inc., a
       Minnesota Corporation.

13.    Limitation of Tenant's Obligations to Replace Rooftop Heating and
       Cooling Equipment:

       If the rooftop heating and cooling equipment cannot be repaired and must
       be replaced in its entirety, Lessor shall be responsible for replacement
       of said equipment.  In consideration of this responsibility, Lessor
       shall have the right





                                     -17-
<PAGE>   18


       to routinely inspect and properly maintain said equipment, and Tenant
       shall promptly pay when due all charges for said inspections,
       maintenance and repairs.

       Upon termination of the initial lease term, and in the event Tenant
       exercises its option to renew, Lessor at its sole discretion shall
       determine whether or not the rooftop heating and cooling equipment and
       unit(s) are to be replaced.  If Lessor so decides, Lessor shall replace
       the heating and cooling equipment and unit(s) and Tenant agrees to pay
       30% of the cost of said new equipment and unit(s).  Tenant's cost shall
       be amortized over the balance of the remaining lease term, payable in
       equal monthly installments, at an interest rate of prime plus 1% per
       annum.

14.    Subordination - Further Agreements
       Lessor agrees to obtain a subordination and non-disturbance agreement
       from existing mortgage holders.  Lessor shall use its best efforts to
       obtain said agreements within thirty (30) days following lease
       execution.  Lesser agrees to provide title evidence showing the names of
       the mortgage holders.

       IN WITNESS WHEREOF, Lessor and Tenant respectively have executed this
Rider to Lease Agreement this 23rd day of February, 1989.

          "Termination





                                     -23-
<PAGE>   24



          Tenant shall have the right to terminate the last two years of the

          "First Right to Lease

          In the event Lessor desires to lease additional space within the
          building of which the Demised Premises is a part, Lessor shall notify
          Tenant, in writing, of same.  Tenant shall respond to Lessor on or
          before seven (7) days after its receipt of the aforesaid notice from
          Lessor whether or not it wishes to proceed with negotiations to
          occupy said space.  In the event Lessor and Tenant are unable to
          agree upon the terms of a lease agreement for said space on or before
          thirty (30) days after Tenant receives notice from Lessor, as
          aforesaid, then Lessor may lease such space to others, provided the
          terms of the lease agreement for such space are the same as or no
          more favorable to the new tenant than those offered by Lessor to
          Tenant.  The obligation of Landlord to offer such space to Tenant is
          a one time right, and having once offered such space to Tenant and
          then leased it to a third party, Landlord shall have no further
          obligation to Tenant to offer such space to Tenant."

          The Lease Agreement, as amended hereby, is hereby ratified and
affirmed by Landlord and Tenant.

          In addition to the amendments set forth above, Landlord and Tenant

upon execution of this Second Amendment; and b) $15,423.00 to be paid on July
1, 1995.  Tenant acknowledges that TMW Real Estate Management, Inc. has
represented Landlord in connection with this Second Amendment and shall be
compensated by Landlord pursuant to a separate agreement.

          This Second Amendment shall have no force and effect and shall not be
binding on Landlord unless and until Tenant delivers to Landlord a duly
executed Reaffirmation of and Amendment to Guarantee in the form attached
hereto as Exhibit "A" and by reference incorporated herein.

          This Second Amendment shall be governed exclusively by the provisions
hereof and by the laws of the State of Minnesota.

Employer and its operation of business and all objects related thereto are and

Employee shall remain the owner of any invention for which no equipment,

     Employer or (2) to the Employer's actual or demonstrably anticipated
     research or development; or

     maintenance, depot computer repair, and computer refurbishment and
     reconfiguration, either as an individual for his own account, or as a
     partner or joint venturer, or as an employee, agent, or salesman for any
     person, or as an officer or director of a corporation or otherwise,
     provided, however, that nothing prohibited by this covenant shall apply to

     stock of any corporation that may be deemed to compete with Employer,
     except that if such stock is not listed on any national or local exchange
     at the date of this Agreement, Employee shall be limited to owning not
     more than 10% of the outstanding shares of any such company.  Solicitation
     or acceptance of business shall constitute "engaging in business" in
     violation of this Agreement.  Except as qualified herein, this covenant on

<PAGE>   11


          (c)    Induce or attempt to induce any customer, supplier, licensees
     or business relation of Employer or its subsidiaries to cease doing
     business with Employer or its subsidiaries or in any way interfere with
     the relationship between any customer or business relation of Employer or
     its subsidiaries.
In the event of a breach or threatened breach by Employee of the provisions
hereof, Employer shall be entitled to seek an injunction restraining Employee
from competing with Employer.  Nothing herein shall be construed as prohibiting
Employer from pursuing any other available remedy for such breach or threatened
breach, including the recovery of damages.  Employee acknowledges and agrees
that a breach of any of the foregoing covenants shall entitle Employer to
withhold and retain any and all amounts owed or to be owed by the Employer to
the Employee pursuant to Paragraphs 5, 6, and 9, in addition to obtaining such
damages and/or injunctive relief, as may be available at law or equity.

                                     -11-
<PAGE>   12


and geographic area specified.  If, however, such terms, covenants or
conditions are found by any court of competent jurisdiction to be unreasonable
because they are, or any one of them is, too broad, then such terms, covenants
or conditions shall nevertheless remain effective, but shall be considered
amended as to the scope of business activities, time and geographic area
specified in whatever manner is considered reasonable by that court, and as so
amended shall be enforced.

but not more than once every year, Employee agrees to undergo an examination by
a physician of Employer's choice, such examination to be at no cost to
Employee.
     16.  Additional Documents.  The parties shall each, without further
consideration, execute such additional documents as may be reasonably required
in order to carry out the purposes and intent of this Agreement and to fulfill
the obligations of the respective parties hereunder.
     17.  Waiver.  Any waiver of any term of condition of this Agreement shall
not operate as a waiver of any other breach of such term or condition, or of

referred to as "NSU" or "Optionor"; and Gary L.  Eizenga, hereinafter referred
to as "Eizenga" or "Optionee".
     WITNESSETH:
     WHEREAS, simultaneously with the execution of this Agreement, AMC and
Eizenga have entered into an Employment Agreement; and
     WHEREAS, as an additional incentive to Eizenga, the parties wish to enter
into an agreement whereby Eizenga is awarded options to purchase up to 2.5% of

acquire and retain a proprietary interest in the Company by ownership of its

substantially all of the assets of the Company, or





                                     -18-
<PAGE>   19


          (iii)  any other corporate reorganization or business combination in
which more than fifty percent (50%) of the Company's outstanding voting stock
is transferred to different holders in a single transaction or a series of
related transactions, except as part of a public offering.
     (e)  "Employment Agreement" shall mean the Employment Agreement between
Eizenga, as Employee and the Company, as Employer, of even date herewith.
     (f)  "Initial Public Offering" shall mean an offering of the Company's
Common Stock registered with the Securities and Exchange Commission or the

Bank National Association, St. Paul, Minnesota as its "reference rate", as that
rate changes from time to time.

each Officer, Director or Shareholder who owns more than five (5%) percent of
any class of the equity securities of NSU or the Company, and each joint
venturer and partner of the Company or NSU.  All Subsidiaries of NSU shall be
deemed to be Affiliates of NSU.
     (m)  "Person" shall mean any natural person, corporation, firm,

     (b)  Exercise Price.  The Exercise Price shall be the Book Value per Share

     (c)  Full-time employment necessary.  Eizenga must be a full-time employee
of the Company (within the terms of the Employment Agreement) (except as
provided in Paragraph 4(d)) from the effective date of this Agreement through
each of the Exercise Dates specified in subparagraph (a) above, in order to
exercise the Shares applicable on each respective Exercise Date.
     (d)  Duration of Options.  Each portion of the Option herein granted is
exercisable on its respective Exercise Date as set forth in subparagraph 4(a),
and shall be exercisable until 11:59 p.m. on October 1, 1999, except that in
the event of Eizenga's termination of employment, regardless of the reason for
termination, death, or permanent disability, all options which were otherwise
exercisable as of the date of termination, death, or permanent disability, may
be exercised only for a





                                     -21-
<PAGE>   22


period of ninety (90) days following termination, death or disability, or until
11:59 p.m. on October 1, 1999, whichever date first occurs.
     (e)  Adjustment.  This Option and each separately exercisable portion
thereof shall be subject to adjustment as provided in Paragraph 5(a).
     (f)  Vesting of Shareholder Rights.  Neither Eizenga nor his Successor
shall have any of the rights of a shareholder of the Company until Eizenga
exercises his option or portion thereof as provided herein and pays the
consideration for all shares purchased.
     (g)  Nontransferability of Option.  No Option shall be transferable or
assignable to Eizenga, otherwise than by will or by laws of descent and
distribution and this Option and each portion thereof shall be exercisable,
during Eizenga's lifetime, only by him.  No Option shall be pledged or
hypothecated in any way and no Option shall be subject to execution,
attachment, or similar process.
     5.   Adjustments.
     (a)  In the event that the outstanding shares of Common Stock of the
Company are hereafter increased or decreased or changed into or exchanged for a
different number or kind of shares of other securities of the Company or of
another corporation, by reason of a recapitalization, reclassification, stock
split-up, combination of shares, or dividend or other distribution payable in
capital stock, appropriate adjustment shall be made by the Optionor in the
number and kind of Shares as to which this Option, or portions thereof then
unexercised, shall be





                                     -22-
<PAGE>   23


exercisable, to the end that the proportionate interest of the holder of the
Option shall, to the extent practicable, be maintained as before the occurrence
of such event.  Such adjustment in outstanding options shall be made without
change in the total price applicable to the unexercised portion of the Option
but with a corresponding adjustment in the option price per share.
     (b)  In the event of the dissolution or liquidation of the Company or a
Corporate Transaction, any Option granted under this Agreement shall terminate
as of a date to be fixed by the Company and NSU ("Option Termination Date"),
provided that not less than 30 days' written notice of the Option Termination
Date so fixed shall be given to Eizenga and Eizenga shall have the right prior
to the Option Termination Date to exercise the Option granted hereunder as to
any part of the shares optioned, not previously exercised, i.e. 500 shares,
less shares previously exercised, subject to adjustments.
     (c)  If the Company is the surviving entity in any merger or other
business combination, then this Option, if outstanding immediately after such
merger or other business combination, shall be appropriately adjusted, by the
Optionor and the Company, to apply and pertain to the number and class of
securities which would be issuable to Eizenga in the consummation of such
merger or business combination if the option were exercised immediately prior
to such merger or business combination, and appropriate adjustments shall also
be made to the price payable per Share, provided the aggregate price payable
hereunder shall remain the same.

     (d)  This Agreement shall not in any way affect the right of the Company
to adjust, reclassify, reorganize or otherwise make changes in its capital or
business structure or to merge, consolidate, dissolve, liquidate or sell or
transfer all or any part of its business or assets.
     6.   Method of Exercising Option.
     (a)  In order to exercise this option or any part thereof, Eizenga (or, in
the case of exercise after his death, his Successor) must take the following
actions:
          (i)    Execute and deliver to the Company a stock purchase agreement
in the form of Exhibit A to this Agreement (the "Stock Purchase and
Shareholder's Agreement" hereinafter "Purchase Agreement") (which Purchase
Agreement the Company and NSU also agree to execute and deliver to Eizenga);
          (ii)   Pay the aggregate option price for the purchased shares in
cash.
          (iii)  Furnish to the Company appropriate documentation that the
person or persons exercising the option, if other than Eizenga, have the right
to exercise this option.
     (b)  This Option shall be deemed to have been exercised with respect to
the number of Shares specified in the Purchase Agreement at such time as the
executed Purchase Agreement for such Shares shall have been delivered to the
Company.  Payment of the Option price shall immediately become due and shall
accompany the Purchase Agreement.  As soon thereafter as practical, the Company
shall mail or deliver to Eizenga or to the other person or persons exercising
this Option a





                                     -24-
<PAGE>   25


certificate or certificates representing the Shares so purchased and paid for,
with the appropriate legends affixed thereto.
     (c)  In no event may this Option be exercised for any fractional shares.
     7.   Compliance with Laws and Regulations.
     (a)  The exercise of this Option and the issuance of Shares upon such
exercise shall be subject to compliance by the Company, NSU and Eizenga with
all applicable requirements of law relating thereto and with all applicable
regulations of any stock exchange on which shares of the Company's Common Stock
may be listed at the time of such exercise and issuance.
     (b)  In connection with the exercise of this option, Eizenga shall execute
and deliver to the Company such representations in writing as may be requested
by the Company in order for it to comply with the applicable requirements of
federal and state securities laws.
     8.   Waivers, Amendments, etc.  No amendment to or waiver of any provision
of this Agreement shall be binding unless in writing and executed by NSU, the
Company and Eizenga.  No failure or delay on the part of any party in
exercising any power or right under this Agreement or any instrument executed
pursuant hereto shall operate as a waiver thereof, nor shall any single or
partial exercise of any such power or right preclude any other or further
exercise of any such power or right.

                              EMPLOYMENT AGREEMENT


     This Agreement (this "Agreement"), is made as of May 1, 1992, by and
between Transition Engineering, Inc., a Minnesota corporation (the "Company"),
and Gary M. Doan, an individual resident of Hennepin County, Minnesota
("Executive").

     WHEREAS, Executive has been an employee of the Company since 1988; and

     WHEREAS, the Company wishes to employ Executive to continue to render
services for the Company on the terms and conditions set forth in this
Agreement, and Executive wishes to be retained and employed by the Company on
such terms and conditions.

     NOW, THEREFORE, in consideration of the premises and the respective
undertakings of the Company and Executive set forth below, the Company and
Executive agree as follows:

     1.   Employment.  The Company hereby employs Executive, and Executive
accepts such employment and agrees to perform services for the Company, for the
period and upon the other terms and conditions set forth in this Agreement.

     2.    Term.  Unless terminated at an earlier date in accordance with
Section 9 of this Agreement, the term of Executive's employment hereunder shall
commence on the date of this Agreement and continue until December 31, 1994.
Thereafter, the term of this Agreement shall be automatically extended for
successive one (l) year periods unless either party objects to such extension
by written notice to the other party at least 60 days prior to the end of the
initial term or any extension term.

     3.   Position and Duties.

          3.01   Service with Company.  During the term of this Agreement,
Executive agrees to perform such reasonable employment duties as the Board of
Directors of the Company shall assign to him from time to time.  Executive also
agrees to serve, for any period for which he is elected, as an officer or
director of the Company; provided, however, that Executive shall not be
entitled to any additional compensation for serving as an officer or director.

          3.02   Performance of Duties.  Executive agrees to serve the Company
faithfully and to be the best of his ability and to devote his full time,
attention and efforts to the business and affairs of the Company during the
term of this

Agreement.  Executive hereby confirms that he is under no contractual
commitments inconsistent with his obligations set forth in this Agreement, and
that during the term of this Agreement, he will not render or perform services
for any other corporation, firm, entity or person which are inconsistent with
the provisions of this Agreement.

     4.    Compensation.

          4.01.  Base Salary.  As compensation in full for all services to be
rendered by Executive under this Agreement, the Company shall pay to Executive
a base salary of $85,000 per year, which salary shall be paid on a bi-weekly
(every two weeks) basis in accordance with the Company's normal payroll
procedures and policies.

          4.02   Incentive Compensation.  In addition to the base salary
described in Section 4.01, Executive shall be eligible to participate in any
incentive compensation plans that may be established by the Board of Directors
of the Company from time to time.

          4.03   Annual Bonus.  If, during each calendar year 1992, 1993 and
1994, (i) the Company achieves the financial targets set forth on Exhibit A
hereto and (ii) Executive continues to be employed by the Company, pursuant to
the terms of this Agreement, during the full calendar year in question, then
Executive shall, for each year in which such targets are met, be entitled to
receive a bonus based on the formula set forth on Exhibit A, but in no event
shall such bonus for any given year exceed 40% of Executive's base salary for
such year.  The bonus shall be paid on March 15, in the year following the
achievement of the targets.  At least 60 days prior to the end of each calendar
year beginning in 1994, the Company and Executive shall establish a financial
target for such year and, if such target is met, Executive shall likewise
receive a bonus based on a formula to be established by Executive and the
Company.  In the event of any disagreement regarding the calculation of the
amount of the bonus for Executive, the determination of the Board of Directors
of the Company shall control.

          4.04   Participation in Benefit Plans.  Executive shall also be
entitled to participate in all employee benefit plans or programs (including
vacation time) of the Company to the extent that his position, title, tenure,
salary, age, health and other qualifications make him eligible to participate.
The Company does not guarantee the adoption or continuance of any particular
employee benefit plan or program during the term of this Agreement, and
Executive's participation in any such plan or program shall be subject to the
provisions, rules and regulations applicable thereto.

          4.05   Expenses.  The Company will pay or reimburse Executive for all
reasonable and necessary out-of-pocket expenses incurred by him in the
performance of his duties under this Agreement, subject to the presentment of
appropriate receipts in accordance with the Company's normal policies for
expense verification.

     5.   Confidential Information.  Except as permitted or directed by the
Company's Board of Directors, during the term of this Agreement or at any time
thereafter Executive shall not divulge, furnish or make accessible to anyone or
use in any way (other than in the ordinary course of the business of the
Company) any confidential or secret knowledge or information of the Company
that Executive has acquired or become acquainted with or will acquire or become
acquainted with prior to the termination of the period of his employment by the
Company (including employment by the Company or any affiliated companies prior
to the date of this Agreement), whether developed by himself or by others,
concerning any trade secrets, confidential or secret designs, processes,
formulae, plans, devices or material (whether or not patented or patentable)
directly or indirectly useful in any aspect of the business of the Company, any
customer or supplier lists of the Company, any confidential or secret
development or research work of the Company, or any other confidential
information or secret aspects of the business of the Company.  Executive
acknowledges that the above-described knowledge or information constitutes a
unique and valuable asset of the Company and represents a substantial
investment of time and expense by the Company and its predecessors, and that
any disclosure or other use of such knowledge or information other than for the
sole benefit of the Company would be wrongful and would cause irreparable harm
to the Company.  Both during and after the term of this Agreement, Executive
will refrain from any acts or omissions that would reduce the value of such
knowledge or information to the Company.  The foregoing obligations of
confidentiality, however, shall not apply to any knowledge or information that
is now published or that subsequently becomes generally publicly known in the
form in which it was obtained from the Company, other than as a direct or
indirect result of the breach of this Agreement by Executive.

      6.  Ventures.  If, during the term of this Agreement, Executive is
engaged in or associated with the planning or implementing of any project,
program or venture involving the Company and a third party or parties, all
rights in such project, program or venture shall belong to the Company.  Except
as formally approved by the Company's Board of Directors, Executive shall not
be entitled to any interest in such project, program or venture or to any
commission, finder's fee or other compensation in connection therewith other
than the salary to be paid to Executive as provided in this Agreement.

     7.   Noncompetition Covenant.

          7.01   Agreement Not to Compete.  Executive agrees that, during the
term of his employment by the Company and for a period of (i) twelve months
after termination of such employment, if such termination is effected pursuant
to subparagraphs (ii), (iii)  or (iv) of Section 9(b) hereof or (ii) six months
after termination of such employment, if such termination is effected pursuant
to Section 9(c) hereof, he shall not, directly or indirectly, engage in
competition with the Company in any manner or capacity (e.g., as an advisor,
principal, agent, partner, officer, director, stockholder, employee, member of
any association, or otherwise) in any phase of the business which the Company
is conducting during the term of this Agreement, including the design,
development, manufacture or selling of devices or components related to the
products or services being sold by the Company or solicit from the Company's
customers any business that the Company is capable of performing during the
term of this Agreement or at the time of Executive's termination.  In the event
of termination of Executive's employment pursuant to Section 2 hereof or
pursuant to Section 9(b)(i) hereof, Executive's obligations pursuant to this
Section 7.01 shall terminate upon his termination of employment.

          7.02   Geographic Extent of Covenant.  The obligations of Executive
under Section 7.01 shall apply to any domestic or foreign city in which the
Company
(a) has engaged in business during the term of this Agreement through
production, promotional, sales or marketing activity, or otherwise, or
(b) has otherwise established its goodwill, business reputation, or any
customer or supplier relations.

          7.03   Limitation on Covenant.  Ownership by Executive, as a passive
investment, of less than five percent (5%) of the outstanding shares of capital
stock of any corporation listed on a national securities exchange or publicly
traded in the over-the-counter market shall not constitute a breach of this
Section 7.

          7.04   Indirect Competition.  Executive further agrees that, during
the term of this Agreement, he will not, directly or indirectly, assist or
encourage any other person in carrying out, directly or indirectly, any
activity that would be prohibited by the above provisions of this Section 7, if
such activity were carried out by Executive, either directly or indirectly; and
in particular Executive agrees that he will not, directly or indirectly, induce
any employee of the Company to carry out, directly or indirectly, any such
activity.

          7.05   Other Employees.  Executive further agrees that, both during
the term of this Agreement and for a period of twelve months following
termination of





                                     -4-
<PAGE>   5


his employment, he will not attempt to persuade officers or employees of the
Company to leave the employ of the Company.

     8.   Patent and Related Matters.

          8.01   Disclosure and Assignment.  Executive will promptly disclose
in writing to the Company complete information concerning each and every
invention, discovery, improvement, device, design, apparatus, practice,
process, method or product, whether patentable or not, made, developed,
perfected, devised, conceived or first reduced to practice by Executive, either
solely or in collaboration with others, during the term of this agreement, or
within six months thereafter, whether or not during regular working hours,
relating either directly or indirectly to the business, products, practices or
techniques of the Company (hereinafter referred to as "Developments").
Executive, to the extent that he has the legal right to do so, hereby
acknowledges that any and all of said Developments are the property of the
Company and hereby assigns and agrees to assign to the Company any and all of
Executive's right, title and interest in and to any and all of such
Developments.

          8.02   Future Developments.  As to any future Developments made by
Executive which relate to the business, products or practices of the Company
and which are first conceived or reduced to practice during the term of this
Agreement, or within six months thereafter, but which are claimed for any
reason to belong to an entity or person other than the Company, Executive will
promptly disclose the same in writing to the Company and shall not disclose the
same to others if the Company, within twenty (20) days thereafter, shall claim
ownership of such Developments under the terms of this Agreement.  If the
Company makes such claim, Executive agrees that, insofar as the rights (if any)
of Executive are involved, it will be settled by arbitration in accordance with
the rules then obtaining of the American Arbitration Association.  The locale
of the arbitration shall be Minneapolis, Minnesota.  If the Company makes no
such claim, Executive hereby acknowledges that the Company has made no promise
to receive and hold in confidence any such information disclosed by Executive.

          8.03   Limitation on Sections 8.01 and 8.02.  The provisions of
Sections 8.01 and 8.02 shall not apply to any Development meeting the following
conditions:

          (a)    such Development was developed entirely on Executive's own
     time; and

          (b)    such Development was made without the use of any Company
     equipment, supplies, facility or trade secret information; and





                                     -5-
<PAGE>   6



          (c)    such Development does not relate (i) directly to the business
     of the Company, or (ii) to the Company's actual or demonstratably
     anticipated research or development; and

          (d)    such Development does not result from any work performed by
     Executive for the Company.

          8.04   Assistance of Executive.  Upon request and without further
compensation therefor, but at no expense to Executive, and whether during the
term of this Agreement or thereafter, Executive will do all lawful acts,
including, but not limited to, the execution of papers and lawful oaths and the
giving of testimony, that in the opinion of the Company, its successors and
assigns, may be necessary or desirable in obtaining, sustaining, reissuing,
extending and enforcing United States and foreign Letters Patent, including,
but not limited to, design patents, on any and all of such Developments, and
for perfecting, affirming and recording the Company's complete ownership and
title thereto, and to cooperate otherwise in all proceedings and matters
relating thereto.

          8.05   Records.  Executive will keep complete, accurate and authentic
accounts, notes, data and records of all Developments in the manner and form
requested by the Company.  Such accounts, notes, data and records shall be the
property of the Company, and, upon its request, Executive will promptly
surrender same to it or, if not previously surrendered upon its request or
otherwise, Executive will surrender the same, and all copies thereof, to the
Company upon the conclusion of his employment.

          8.06   Obligations, Restrictions and Limitations.  Executive
understands that the Company may enter into agreements or arrangements with
agencies of the United States Government, and that the Company may be subject
to laws and regulations which impose obligations, restrictions and limitations
on it with respect to inventions and patents which may be acquired by it or
which may be conceived or developed by employees, consultants or other agents
rendering services to it.  Executive agrees that he shall be bound by all such
obligations, restrictions and limitations applicable to any such invention
conceived or developed by him during the term of this Agreement and shall take
any and all further action which may be required to discharge such obligations
and to comply with such restrictions and limitations.

     9.   Termination.

          9.01   Grounds for Termination.  This Agreement shall terminate prior
to the expiration of the initial term set forth in Section 2 or any extension
thereof in the event that at any time during such initial term or any extension
thereof:

                 (a)       Executive shall die.


                 (b)       The Board of Directors of the Company shall
                           determine that:

                            (i)    Executive has become disabled,

                           (ii)    Executive has breached this Agreement in any
                                   material respect, which breach is not cured
                                   by Executive or is not capable of being
                                   cured by Executive within thirty (30) days
                                   after written notice of such breach is
                                   delivered to Executive,

                          (iii)    Executive has engaged in willful and
                                   material misconduct, including willful and
                                   material failure to perform his duties as an
                                   officer or employee of the Company and
                                   including illegal or dishonest acts, or

                           (iv)    Executive has breached his duty of loyalty 
                                   to the Company.

                (c)  Executive is otherwise terminated by the Company (the
                     right to terminate Executive at any time, with or without
                     cause, is expressly reserved by the Company and
                     acknowledged by Executive, subject to the Company's
                     obligations pursuant to Section 10.01 hereof, if
                     applicable).

Notwithstanding any termination of this Agreement, Executive, in consideration
of his employment hereunder to the date of such termination, shall remain bound
by the provisions of this Agreement which specifically relate to periods,
activities or obligations upon or subsequent to the termination of Executive's
employment.

          9.02   "Disability" Defined.  The Board of Directors may determine
that Executive has become disabled, for the purpose of this Agreement in the
event that Executive shall fail, because of illness or incapacity, to render
services of the character contemplated by this Agreement over a period of 90
days during any one year period.  The existence or nonexistence of grounds for
termination of this Agreement for any reason under Section 9.01(b)(i) will be
determined in good faith





                                     -7-
<PAGE>   8


by the Board of Directors after notice in writing given to Executive at least
thirty (30) days prior to such determination.  During such thirty (30) day
period, Executive shall be permitted to make a presentation to the Board of
Directors for its consideration.

          9.03   Surrender of Records and Property.  Upon termination of his
employment with the Company, Executive shall deliver promptly to the Company
all records, manuals, books, blank forms, documents, letters, memoranda, notes,
notebooks, reports, data, tables, calculations or copies thereof, which are the
property of the Company or which relate in any way to the business, products,
practices or techniques of the Company, and all other property, trade secrets
and confidential information of the Company, which in any of these cases are in
his possession or under his control.

     10.  Severance.

          10.01  Severance Payments.  In the event that the Company terminates
Executive pursuant to paragraph (c) of Section 9 hereof (but not in the event
that Executive terminates his employment or Executive's employment is
terminated pursuant to Section 2 hereof or paragraphs (a) or (b) of Section 9
hereof), the Company shall pay to Executive his base salary, as then in effect,
for a period of six months following the date of termination.  Executive
acknowledges and agrees that his sole right to receive compensation pursuant to
this Agreement following any termination shall be limited to the severance
payments described in this Section 10.01.

     11.  Miscellaneous.

          11.01  Governing Law.  This Agreement is made under and shall be
governed by and construed in accordance with the laws of the State of
Minnesota.

          11.02  Prior Agreements.  This Agreement contains the entire
agreement of the parties relating to the subject matter hereof and supersedes
all prior agreements and understandings, whether oral or written, with respect
to Executive's employment with the Company and any rights to acquire an
interest in the Company, specifically including that certain Transition
Engineering, Inc. Employment Agreement, dated January 29, 1988, that may or may
not have been executed by Executive and the Company, but which Executive and
the Company agree is hereby terminated, void and of no further force or effect.
Except for that certain Stock Option Agreement, of even date herewith, between
the Company and Executive, the parties hereto have made no agreements,
representations or warranties relating to the subject matter of this Agreement
that are not set forth herein.





                                     -8-
<PAGE>   9


          11.03  Withholding Taxes.  The Company may withhold from any benefits
payable under this Agreement all federal, state, city or other taxes as shall
be required pursuant to any law or governmental regulation or ruling.

          11.04  Amendments.  No amendment or modification of this Agreement
shall be deemed effective unless made in writing and signed by the parties
hereto.

          11.05  No Waiver.  No term or condition of this Agreement shall be
deemed to have been waived, nor shall there be any estoppel to enforce any
provisions of this Agreement, except by a statement in writing signed by the
party against whom enforcement of the waiver or estoppel is sought.  Any
written waiver shall not be deemed a continuing waiver unless specifically
stated, shall operate only as to the specific term or condition waived and
shall not constitute a waiver of such term or condition for the future or as to
any act other than that specifically waived.

          11.06  Severability.  To the extent any provision of this Agreement
shall be invalid or unenforceable, it shall be considered deleted herefrom and
the remainder of such provision and of this Agreement shall be unaffected and
shall continue in full force and effect.  In furtherance and not in limitation
of the foregoing, should the duration or geographical extent of, or business
activities covered by, any provision of this Agreement be in excess of that
which is valid and enforceable under applicable law, then such provision shall
be construed to cover only that duration, extent or activities which may
validly and enforceably be covered.  Executive acknowledges the uncertainty of
the law in this respect and expressly stipulates that this Agreement be given
the construction which renders its provisions valid and enforceable to the
maximum extent (not exceeding its express terms) possible under applicable law.

          11.07  Assignment.  This Agreement shall not be assignable, in whole
or in part, by either party without the written consent of the other party,
except that the Company may, without the consent of Executive, assign its
rights and obligations under this Agreement to (i) any corporation, firm or
other business entity which controls the Company, specifically including
Americable, Inc., presently the sole shareholder of the Company, and North Star
Universal, Inc., presently the sole shareholder of Americable, Inc. and (ii)
any corporation, firm or other business entity with or into which the Company
may merge or consolidate, or to which the Company may sell or transfer all or
substantially all of its assets, or of which 50% or more of the equity
investment and of the voting control is owned, directly or indirectly, by, or
is under common ownership with, the Company.  After any such





                                     -9-
<PAGE>   10


assignment by the Company, the Company shall be discharged from all further
liability hereunder and such assignee shall thereafter be deemed to be the
Company for the purposes of all provisions of this Agreement including this
Section 11.

          11.08  Notices.  All communications and notices provided under this
Agreement or any instrument executed pursuant hereto shall be in writing and
sent by first class certified mail, and if to the Company, addressed and
delivered to it at:

notice to the other parties.  Any notice, if mailed properly addressed, shall

          11.09  Injunctive Relief.  Executive agrees that it would be
difficult to compensate the Company fully for damages for any violation of the
provisions of this Agreement, including without limitation the provisions of
Sections 5, 7, 8 and 9.03.  Accordingly, Executive specifically agrees that the
Company shall be entitled to temporary and permanent injunctive relief to
enforce the provisions of this Agreement and that such relief may be granted
without the necessity of proving actual damages.  This provision with respect
to injunctive relief shall, however, diminish the right of the Company to claim
and recover damages in addition to injunctive relief.

previously purchased pursuant to the Option, subject to adjustments.

Option Exercise Price, provided the aggregate Exercise Price payable hereunder
shall remain the same.

the Company to adjust, reclassify, reorganize or otherwise make changes in its
capital or business structure or to merge, consolidate, dissolve, liquidate or
sell or transfer all or any part of its business or assets.

     as defined in Section 2(c) of the Stock Option Agreement.

     2.    Exercise of Option.

           (a)   Exercise.  Doan hereby purchases ____________ Shares (the
     "Purchased Shares") at an exercise price of $______________ per Share,
     (the "Exercise Price") pursuant to the Stock Option Agreement.

           (b)    Payment.  Concurrently with the delivery of this Agreement to
     the Company, Doan shall pay the Exercise Price for the Purchased Shares in
     accordance with the provisions of the Stock Option Agreement and shall
     deliver whatever additional documents may be required by the Stock Option
     Agreement as a condition for exercise.

     3.    Investment Representations.

           (a)   Investment Intent.  Doan hereby warrants and represents that
     he is acquiring the Purchased Shares for his own account and not with a
     view to their resale or distribution and that he is prepared to hold the
     Purchased Shares for an indefinite period and has no present intention to
     sell, distribute or grant any participating interests in the Purchased
     Shares.  Doan hereby acknowledges the fact that the Purchased Shares have
     not been registered under the Securities Act of 1933, as amended (the
     "1933 Act"), and that the Company is issuing the Purchased Shares to him
     in reliance on the representations made by him herein.

           (b)   Restricted Securities.  Doan hereby confirms that he has been
     informed that the Purchased Shares may not be resold or transferred unless
     the Purchased Shares are first registered under the Federal securities
     laws or unless an exemption from such registration is available.
     Accordingly, Doan hereby acknowledges that he is prepared to hold the
     Purchased Shares for an





                                     -11-

     indefinite period and that he is aware that Rule 144, as promulgated under
     the 1933 Act, is not presently available to exempt the sale of the
     Purchased Shares from the registration requirements of the 1933 Act.
     Should Rule 144 subsequently become available, Doan is aware that any sale
     of the Purchased Shares effected pursuant to Rule 144 may, depending upon
     the status of Doan as an "affiliate" or "non-affiliate" under the rule, be
     made only in limited amounts in accordance with the provisions of the
     rule, and that in no event may any Purchased Shares be sold pursuant to
     Rule 144 until Doan has held the Purchased Shares for the requisite
     holding period following payment of the Option Price for the Purchased
     Shares.

     4.    Restrictions on Sale or Transfer.

           (a)   General Prohibition on Transfer.  Until such time as the
     Company has successfully completed an Initial Public Offering, neither
     Doan, his Successor, or his Involuntary Transferee shall dispose of,
     encumber, or transfer any of the Company's Shares now owned or in the
     future acquired, without the Company's prior written consent and the
     Shares must be transferred as set forth in subparagraph (b) below.  Any
     purported transfer or disposition of Shares in violation of the terms of
     this Agreement shall be void, and the Company shall not recognize or give
     any effect to such transaction.

           (b)   Granting of Certain Purchase and Sale Rights Regarding the
     Shares.

                 (i)  Type A Events - Procedures.
